The quadrajet is hands down the best driving 4 barrel carb ever. The factory used the nice light carb return springs so the gas peddle is very easy to push and the secondarys transition so smoothly and so nice and when they are right you can floor them from a dead stop with absolutely no hesitation.
I have a rochester 800 cfm on my SBC 406 for 35 Years and just put a Kit through it now the car has brute acceleration and ok economy and it sounds so great hearing the air rush into the Carby.Then you open up the secondary's party time.
rochester carbs are the best for tuning and drivability i like the fact they only come in 2 flavors but fit every carbureted gm v8 ever made but i do own this holly that's so rare i can't find it on the web it's a double pumper dual feed mechanical secondary 2 piece that splits just like a rochester it's gotta be some kind of circle track or maybe off road it's polished aluminum it came with a 454 i bought a while back and that thing rocks takes 5min to change jets you can change every part with out even draining the fuel except the 2 diaphragms for the accelerators 4 jets and 2 power valves the throttle response is amazing when i run it on my 73 cheyenne c30 4 door dually 9' box i have to almost let it coast out of first or it wants to do massive burnouts it's like driving a stunt truck.
That rod people pull off is kind of a safety device to keep the secondary from going wide open when the engine is cold. The choke has a complete lockout when fully closed because it is going to lean out and bog if you put warm engine air fuel ratio in a cold motor. When the choke is partially closed it creates vacuum above the primaries. This vacuum limits the amount that the secondary air doors can open. As the choke opens up the doors open more until engine vacuum opens them as much as it needs. It just won't work right without it. Q-jets have everything, altitude and temperature compensation, the works. You won't get that on a Holley or an Edelbrock. It really is as close to efi as you can get if it is tuned properly.
It's so refreshing to see someone who truly appreciates what a good carburetor the Quadrajet really is. I run into people who call them "quadrajunk" all the time and say how not only were they shitty when they got them but they were even shittier after rebuilding them. There are a decent amount of moving parts on a Quadrajet and if you don't really know what you're doing, you'll screw one up pretty bad. The Rochester Quadrajet is hands down, my favoriye 4bbl carb and you can do wonders with them IF YOU KNOW WHAT YOU'RE DOING. LOL. Keep these videos coming to spread the word that these misunderstood carbs are in fact awesome! Holleys are okay and so are Edlebrock/Carters but the Qjet is my pick,,,plus they don't need constant tuning.
Love your video and I totally agree with you that Quadrajets are an excellent design. I've had small blocks, big blocks equipped with them and they always performed very well. I was taught a long ago about the does and don'ts of these carburetors you all absolutely right. They are many things that you can do to get extreme performance out of these. An old timer taught me about them when I was in my late teens and with patience and common sense, you can achieve incredible performance and lightining quick secondary response. So many people give these carburetors a bad rap and if they simply took the time to LEARN about them, they would realize what great, simple, economical carburetor they really are. Thanks for sharing your video.
Want to say thanks! I just cleaned and rebuilt mine with the help of your vids. This quadrajet was in my GMC g3500 motor home with a 454. As soon as the bowl was filled it fired right up and ran great! I will take it for a run tomorrow. It was not very dirty (compared to the ones you show) but the power piston "T" needle holder was bent and a secondary tube was dropped. Before I rebuilt It it ran real rich and stalled at lights. Float was set right so hoping that will no longer happen. I think the uneven primary needles were the problem. And the dropped secondary tube made hill climbing a pain. Also would sputter in sharp right turns. If it still gives me problems I will look at a coil. But I have a feeling this was the issue. Keep up the good work. Thanks again.
Tyler I put a carb of a 307 on a 403. What do I have to do to make it run right? Where do I get bigger secondary jets? Do I have to? The carbs actually made out of a bunch of different junk yard carbs. Maybe I should just get another carb. It’s in a 57 buick. I think there’s a video of it on my channel if you want to see.
Nice work. I'm a little older and come from the Quadrajet era. I have heard everything there is to hear about QJ's over the years. I know from experience they are excellent when working properly. My first experience was with my friends 1969 Chevy Impala. We were 15 in 1974 and this car was a rocket. We of course, flipped the air cleaner cover up side down and engaged the secondaries OFTEN. What fun. Then there are the horror stories and I was sucked in as well. Getting stuck with someone else carburetor misgiving is a NiGhTmArE...Now I have one on a 1920 Hudson roadster I built and LOVE IT. It's my FIRST CHOICE, go to carb especially for GM engines. Love the spread bore efficiency. Great fuel economy if you can keep your foot out of it. Yet, if you cant keep your foot out of it, what FUN. Mine came off of a 1980 Cadillac Fleetwood with a 368 big block. All I had to do was put a little bigger rods in the secondaries and readjust the front jets and idle. Unless your at the track, don't screw with your QJ. Even then, QJs work well there too. Thanks for the great vids. I've reacquainted myself with QJ info... By the way Tyler, you're about the best overall QJ guy I could find on the internet.
I like a slight bog lol run it up.in rpms a lol bit then jump.in it kicks like.a.mule adjust the air doors with the spring so they don't bounce lol but I like the kick feeling and not the no feeling at all between the primaries and secondary
I've been preaching Q-jet to the Holley and Edelbrock sheep since i was a teenager... I learned to appreciate them early on and made more than a coin or two on tuning them and on wagers that i could make HP with them.. I have been known to tune them right out on the water in Marine applications.. don't ask how many times I've dropped that hangar screw down in a bilge.. added a nice supply of them to my metering rod, jet and spring kit... air horn removal on a choppy lake is no fun either.. but I'm not gonna let an innocent q-jet get trashed over a bad tune or at the hands of a cam swap king.. Hands down the best marine and street carb ever.. and I'd say strip also since i've made 600 HP+ with them on several engines.. I still find one on the bench occasionally.. right next to the injector flow bench..
I really enjoy your quadrajet videos you have alot of good info. I used to think I hated them but after I picked one up for my 72 impala and had it rebuilt by a local quadrajet tuning mechanic I actually found it to be quite impressive and probably will never go back to an edelbrock. The quadrajet jet just runs so much better than the 1406 edelbrock that I had. And you definately make good points about people trying to so called "performance" mod them in the back yard cause all the dampeners and control rods wouldn't be there if they weren't absolutely necessary for the proper operation of the carb. Theyvare great carbs thanks for the videos
Man I really appreciate you making this video man. I was considering getting a edlebrock for my 307 cuz I was under the impression that quads wernt the best, but youve made great since in explaining why they ARE good carbs. Now Ill rebuild mine this summer and put it right back on my car... Thanks!!!
Great video, glad I found your channel. Plan to rebuild the Qjet on my 78 Silverado. 400 beneath it is a bit built, but the poor girl has been sitting way to much. Looking forward to bingeing on more of your videos
Appreciate the info. I've always been standoffish to the Q-Jets and believe I've even made that air door spring tension "tech-tip" in my youth on the advice of others. I have educated myself on Holleys over the years because that's what I was using on the old cars then. Well, today I have a LeMans and we're swapping out the 350 for a 400 and I have been given an unmolested Q-Jet for it and I'm poor so that's what i'm working with so I need to learn something new now. I found your video in my quest for this knowledge and you made some spectacular safety points that it has in it's advantage concerning the accel pump and bowl gasket leaks, both of which I know well enough. I appreciate your sharing these point as well as the other many design improvements it has for me. I can hardly wait to get familiar with them now! (and toss that old thinking!)
Thank you for this video; I have a Quadrajet on the 1986 GMC truck. I have been patient to gather information before touching it because i have some low rmp bog. Doesn't create too much problem because i drive her mellow, but i do enjoy helping machines work properly and still not sure what she needs. I am delighted you mentioned the dampener, i was JUST wondering what that was :)
Your videos are the best! Thanks alot for taking the time to make these videos and helping people out! WIsh there was an email to contact you-but then again, it would be a full time job answering alot of emails all day! Im trying to respond to a reply you sent to my question-about metal shavings found in the inline fuel filter...........
I raced dirt track 10 years ago and won a championship with a quad built by a old timer. Here i am now building another car but the old timer is gone, so it on me. My newer quad doesn't have the air door dampener. you think it will be be fine or should i try to source one. i should be turning around 6000rpm or more with around 350hp with a high rpm cam.
BTW, I wonder about the 5 dummies who gave a thumbs down. WTH is there not to like. If you have a Quadrajet, Tyler's videos are a MUST.... Otherwise you MUST be in the wrong place. So, to those five dummies, "I fart in your general direction!"
+WhoSaidTyler good video. primary metering rods (a-b) a=single taper b=double taper emissions rod same thing on secondary side. the make different accelerator pump stems power valve springs needle and seats big block CARB's have different size air bleeds. emulsion tubes etc. small block CARB's do good on a big block up to 3300-rpm app big block CARB's on a small block -not so great. Q-JET'S are fine CARB's until warped etc from over tightening etc don't use gasket stack's. heated air and manifold help emissions, drivability, distribution, economy, etc keep up the good work TAKE CARE.
+WhoSaidTyler on the primary side they make A-rods=single taper/performance B-rods=double taper/emissions same on secondary metering rods single taper -perfomance double taper=emission. the dampers have a metering hole to determine how fast the secondary air door opens there a great Carb!!! copied to some extent by Carter/Holley Etc. you don't copy junk. Quadrajet's are timeless A TRULY GREAT CARB !!! NEVER USE A BRASS FLOAT. there not as buoyant. I learned that the hard way back in 1985. a stock float is fine. THANKS FOR GIVING QUADRAJET'S THE RESPECT GT THEY DESERVE TAKE CARE.
I have a 383 with an AVS2 Edelbrock carb . I can adjust the rear door flap so I tightened it up so that it wouldn't open . Right away I noticed way better gas mileage . power is addictive and youll always wanna hold the throttle so the rpm opens the carb and pulls you back in your seat . But if your just cruising you make that flap much harder to open so it doesn't get into the power as quick and it really makes a huge difference . I had a quadrajet for like 10 years , loved that carb and I can see now how great it really was . Those tiny primaries would give awesome cruising torque and mileage . And the roar of the massive secondary's opening was awesome . It would be cool to see what my old carb and edelbrock performer would do on this engine . I think the engine would run out of breath to early for the cylinder heads im running now .
The vacuum secondary on a Holley gives variable cfm. It runs off Venturi vacuum, not manifold vacuum. As airflow through the primaries goes up, it opens the secondaries to balance the spring tension in the vacuum pot. Once the engine is flowing all the air it wants, the secondaries stop opening.
First carb I rebuilt was the QJ on my '67 Chevy,about,oh,10 years ago. People thought I was nuts,and would never get it running again. It wasn't hard,I dunno what the fuss is about. The car has been running fine (even better!) ever since. It's been a great carb,and has no issues feeding the 327 under it.
The choke can be a bit fiddly to adjust,but once it's fiddled right,it's generally fine,in December with snow on the ground,or July,when it's over 100 degrees.
If you could in the video explain to your knowledge how well it does off-roading I’ve herd threw the grape vine it’s one of the best for off-roading but you seem to really know your Shit so hearing it from you would really help me make up my mind on whats going on the ramcharger my eddlebrock does ok but I fucked with the secondaries and I want something better
Very good info I've heard so many people talk crap about these but my obb always runs better with the original carb I've had big dollar Holly's on it and on the street it's a finicky/ leaky carb that's not a good start in the cold with a full race valve train but the old quadrajet always starts cold and I don't have to baby sit a cold engine with it. Great video I learned more about this awesome carburetor!
Thanks for sharing your information on Quadrajets, I've always been fascinated by carburetors and my friends would always tell me Q-Jets were junk, I always believe they were an awesome factory carb. My uncle has been trusting them for years and I guess I just lived on knowing they are awesome.
The first car I owned was a 1984 Pontiac Bonneville. Chevrolet 305cid, 4bbl Rochester Q-Jet E4ME. I rebuilt that carb when I got the car, having never touched anything bigger than a lawn mower carb in my life, and I ran that car for 10 years without any problems. I know the guy who owns it now, and it's still running the same carb. No issues whatsoever. I'm not hating on holley or edelbrock, if you like them, more power to you, but I'll run a Q-Jet before I run anything else if I have any choice in the matter. Excellent video! (BTW, I have a 1982 Chevy C10 Silverado now with the 305 and a 4bbl Q-Jet, and runs just as good as my old pontiac did.)
Tyler Love your videos, very helpful. I do have a question though. You talk a lot in this video about the secondary air doors being too loose and people having thin needles causing that notorious bog. My question, (maybe I'm not thinking correctly) if the doors are to tight and/or the needles are to fat it would starve for fuel.....correct? Reason I ask is I have a c20 suburban with a 454, 800cfm qjet and it starts to crack and pop when I open the 4 barrel, especially I colder weather. Freshly rebuilt motor (timed correctly) and carb.
People don't know how to tune them and most are old. So the pump plunger is dry rotted. They smash foot to the floor and car falls on its face. So instead of getting a rebuild kit and a float for 20 bucks they say Q jets suck lol 😂. I agree with you, it's definitely the most idiot proof carburetor you can get. I laugh when people go buy a 750 holley because they had a 750 Q-jet. It runs, but they are losing a ton of power and running fat.
The "thing a ma jiggy" is the Idle Pickup Tubes. Is there a way to remove them for cleaning or just shoot some carb cleaner into them? Im also thinking the metal shavings may have come from a metal tube brake line that I used as a fuel line going from the fuel pump, going up the engine block ( behind the water pump) and then the pipe turns toward the carburetor where I have an in line filter. Im taking a guess but maybe there was some metal shavings in the metal tubing from when I cut it to fit into place. I cant think of anything else that would make sense. And no-I didnt clean the tube before installing it! Crap!
where do i plumb my pcv breather valve to ? I have plumbed it to the large port beside the fuel intake rh side on the stuby pipe hanging out there. Andrew
yes they r a great carb i've rebiult many of them most of all is the mpg u get with these carbs I never had a problem unless someone before me got a hold of it or it sat a long time so time for a freshing up
Just bought a 455 olds bored out with the Quadrajet, also just rebuilt it, getting ready to install tomorrow, but did notice where fuel line goes into the front, the threads are stripped😒, any suggestions on this fix, or do I need to buy a new part?
I believe there is a repair kit for this sold online. If they are really bad, you can resort to an epoxy repair such as JB weld, but do so at your own risk. That will also require using an external filter. Remember that there is a nylon gasket that goes over the fitting to seal it. Lots of times these strip because people neglect that item and keep cranking down on it.
+Juday Hajri (الشيخ جديع خالد الهاجري) usually 3 possibilities: the choke isn't opening, the float is set too high, or the inlet needle isn't shutting the fuel flow off because of dirt or debris on it.
I have a qjet with a pontiac fuel inlet on a Chevy 350 engine and the hard fuel line is screwed up and cut off and a rubber hose is ran to the pump. How would you recommend remedying this?
@@TylersNeighborhoodGarage had to get a right angle inlet banjo adapter and then bought a stock corvette carb to pump fuel line. About $25 each part. The straight inlets were made for pontiac/buick engines and the right angle inlets were for chevy/GM. Chevy GM have the thermostat housing right in front of the carburator but with pontiac it was off to the side, so it's difficult to service the fuel line if you have a pontiac qjet on chevy sbc and it also heats up the fuel line being right up against it. It was all bent up and chewed up from people formed owner or mechanic. Looks clean now.
I need to rebuild a q jet for my 77 L82 man trans. I have seen and saved all your previous vids for rebuilds. I have a kit but don't think it's the same full kit I would like to use. Do you have a kit recommendation? I may need to message you later for more questions if ok. Thanks Tyler
Can you do a video on a properly working Rochester which shows the secondaries opening correctly? I heard you say the secondary doors aren't suppose to open fully. Mine don't open fully and I thought there was a problem with the linkage located behind the electric choke which connects to the piece that stops the lower secondaries from opening. I think Ive watched all your videos and cant find a video which shows how the linkage behind the electric choke is suppose to be connected. I think my secondaries don't open because the linkage isn't releasing the lower seondaries from opening and therefore, the upper secondaries wont open
i have a 78 chevy silverado sb pu 350 v8 ,it has all stock ,but i have a edelbrock performer intake nd thinking of installing it but i was wondering should i just replace the q-jet nd put a edelbrock carb with 600cfm on the edelbrock intake or just rebuilding the q-jet nd put on e intake ?
Your truck is the same as mine, and the engine under WHATEVER intake and carb you put on is still a low-compression, 165hp slug. Not saying that to be mean but it's the truth for both of us. Unless you install an engine with much better heads and cam, or build that one I wouldn't waste time on a carb swap. My 350 runs extremely reliably with it's rebuilt factory Qjet.
To expand on the other comment...that engine has 882 heads, which have huge combustion chambers and a cam that runs out of breath at about 3900 rpm. It's perfect for a truck. Putting an intake on it will give you more imaginary horsepower than real ones. If you want it to run, strip it to the shortblock and start over. Vortec heads, good matching cam and your choice of intake and carb.
I have one of these Qwad 4's on my 1985 Pontiac 305 it is original and works perfect . I like it ! But do not take it to a service station that dose not know what they are doing . You are just going to have to do your homework and know that you are leaving your car with someone who knows . Don't be stupid when you come back to pick it up and pay for it you just mite be GOING TO COURT !!! ~ hard life (MULDEW) ~ gary b *
I'm a big QuadraJet fan they are very tunable things that will work on any engine from 229 v6 to 500 Cadillac v8s I wish more people liked them but at the same time it's fun after beating someone in a small town backroad race getting to say you've just been beat by a QuadraJet.
Hey Tyler, Great videos. I'm getting ready to watch your videos on the rebuild of the Qjet. Looking forward to running it on a LQ4 just for kicks. Loved the sound of these when I was younger. Keep up the good work. Any suggestions just in case or where you get parts?
I just found a quadrajet in y shed dont know what it was doin with the ford parts i have. Anyway, it has a lever swing that locks the big plates from moving when the carb is tilted toward the big plates side and doesn't allow for wide open throttle. Why is that? The carb i have has has the rat tail coming out sideways towards the choke side and manual choke looks like because it doesn't have that black piece and the older looking black piece.
The lever that blocks the plates is operated by the choke. When the choke is engaged(cold engine), it prevents the secondaries from opening and potentially causing a backfire. If you provide the numbers stamped vertically on the left side I can tell you what it came on.
i have had many many edelbrocks even a few hollies and nothing i do mean nothing beats my computer control quadrajet have on the 350 i have now ........we switched it over from the 305 it was originally used on........ no issues at all great performance and fuel economy that no after market carb i ve found yet can match............ who needs efi right lol
I have a 305 in a 89caprice...when i turn corners sharp it burns a little rubber but the whole car shuts off then comes back on..maybe battery or carb?? Let me know thanks
I really like your 2 videos about the Quadrajet. There is a company called Garanteed Carburetor. They sell rebuilt carbs and one of them is the Quadrajet. I have a Chevy 454 V8 in a 27ft Winnebago. It is a 1989 motorhome. The vehicle has 98k miles on it. The price of the carb is 265.00....any advice? It is a California vehicle but I don't live there anymore. David 🐈
so you can change your secondary mixture ( Wide open dyno testing) without tearing the carb down? NICE! ...just bought a 750 quadrabog today for 20 bucks, watching this shit to see what i got myself into ....So...is the "bog" a lean bog, or rich bog....thanks.
It's a combination of both. The air doors act directly on the secondary rods, and also affect the secondary pullover enrichment system. When the airdoor tension adjustment gets screwed up by a well-meaning but un-informed person, the airdoors slam open, bounce back nearly closed, slam nearly open again, repeat. So, the airflow and fuel metering is all over the place while the secondary throttle blades are hanging there wide open the entire time. Rochester designed the airdoor tension operation and airdoor damper for a reason and it wasn't to restrict performance. Guys can lecture on Holley vacuum secondary operation all day long but they can't figure this simple system out. Thanks for watching!
so this "bog" is really just a combination of lean and rich then...that can be fixed by a correct actuation of the air flap...i was under the impression the "bog" is either a lean condition or rich condition, not a combination...tell me if i'm wrong...thanks. I just started watching your first video now , after i posted this. Thanks.
@whosaidtyler i need educated on chokes thats on my carb, my boat has a 305 chevy low block and no im not a mechanic ,but willing to learn and im having trouble , im told im messing a linkage on the choke , so my question can i get a kit to replace the choke , please help me
I need some more info: 1. The carb # which is located on the port side of the carburetor, running vertically behind the throttle linkage. It's stamped, not raised letters. 2. Is it electric or hot air choke 3. What problems are you having? Thanks.
@ who said Tyler I have a 87 Caprice with a 305 motor and when I go up to 45 miles per hour it surge what could cause this to happen with my car I change the fuel pump spark plugs wires and still the same problem
you my good man helped me out. I can give the edelbrock carb back and just find a Quadrajet with out the stupid electric components. I have an 86 gmc g2500 and the stupid air fuel control solenoid I want to get rid of.
That's not an air/fuel solenoid. It's a dual capacity accelerator pump. If you leave it unplugged works just like any other qjet. It's a good 800cfm carb. 3/4-ton trucks did not have the same electronic controls and emission controls as cars and light duty trucks.
i kept it unplugged and its not running any good with or with out it plugged. If i full throttle it it bogs bad like its starving for fuel but i have replaced everything from filters to fuel pump. When it idles it smell as ifnits pumping to much gas. When i look up the part to see how much they cost they called it a mixture control solenoid. Im at a loss with it.
im watching your computer controlled quadrajet video ( Understanding computer-controlled Quadrajets part 1 of 3 ) you start talking about it at video mark 10:23. that's the part im having trouble with.
Aaron Silvious Sure. If you go to my channel page and click on the "about" button, it should give you an option to send me a pm. Let me know what you are planning and I'll advise you.
WhoSaidTyler it doesn't give me that option, only shows your followers and videos, etc. My email is aaronsilvious@gmail.com and it's not spam, scout's honor
Years ago I got an engine trans unit out of a motor home. today after watching the decoding video I decided to go get the carb and see if it was the original to the 454 chevy engine and 400 trans from the motor home. I don't think it was. 17059530; 3218 julian.
You really can't. The internal calibration is way too lean for a big cube engine, plus it very well be the smaller 750 cfm version. Look for a 500 cid Cadillac Qjet as a starting point instead.
Ok Thsnks for the heads up. I was thinking of just jetting it up by looking up the specs for the 500. Lol I have 3 carbs that cane off sbc and love to use them. But thanks for the heads up.
watching a guy on another forum explaining how much better his runs with the secondary air doors removed...of course he bought it this way, so he has no idea how it runs WITH the air doors installed
You can buy any of that. Quadrajetparts.com has all of it. The Cliff Ruggles book on Qjets is a must-have. If that's still the original carb on that 400, those are about the best of the best.
@@donaldgreen7471 you are correct sir. As an old school mechanic and I worked at a Corvette shop most vehicles didn't have a Q jet as standard equipment until 68. Corvettes came with a holley until 68. I stand corrected. Thank You.
Great Video again WhosaidTaylor love watching them. I've been looking for an answer to why mine floods. It stalls and then fuel spills out over the top of the Carb. At a guess this is a problem with the inlet seat. I did have a mechanic look at it some time back and he cleaned it out and gave it a 'not the best example he has seen type comment'. Am I heading down the right track.? I cut a utube video if you are interested to have a look.
The quadrajet is hands down the best driving 4 barrel carb ever. The factory used the nice light carb return springs so the gas peddle is very easy to push and the secondarys transition so smoothly and so nice and when they are right you can floor them from a dead stop with absolutely no hesitation.
I have a rochester 800 cfm on my SBC 406 for 35 Years and just put a Kit through it now the car has brute acceleration and ok economy and it sounds so great hearing the air rush into the Carby.Then you open up the secondary's party time.
rochester carbs are the best for tuning and drivability i like the fact they only come in 2 flavors but fit every carbureted gm v8 ever made but i do own this holly that's so rare i can't find it on the web it's a double pumper dual feed mechanical secondary 2 piece that splits just like a rochester it's gotta be some kind of circle track or maybe off road it's polished aluminum it came with a 454 i bought a while back and that thing rocks takes 5min to change jets you can change every part with out even draining the fuel except the 2 diaphragms for the accelerators 4 jets and 2 power valves the throttle response is amazing when i run it on my 73 cheyenne c30 4 door dually 9' box i have to almost let it coast out of first or it wants to do massive burnouts it's like driving a stunt truck.
That rod people pull off is kind of a safety device to keep the secondary from going wide open when the engine is cold. The choke has a complete lockout when fully closed because it is going to lean out and bog if you put warm engine air fuel ratio in a cold motor. When the choke is partially closed it creates vacuum above the primaries. This vacuum limits the amount that the secondary air doors can open. As the choke opens up the doors open more until engine vacuum opens them as much as it needs. It just won't work right without it. Q-jets have everything, altitude and temperature compensation, the works. You won't get that on a Holley or an Edelbrock. It really is as close to efi as you can get if it is tuned properly.
Thanks.
It's so refreshing to see someone who truly appreciates what a good carburetor the Quadrajet really is. I run into people who call them "quadrajunk" all the time and say how not only were they shitty when they got them but they were even shittier after rebuilding them.

Keep these videos coming to spread the word that these misunderstood carbs are in fact awesome! Holleys are okay and so are Edlebrock/Carters but the Qjet is my pick,,,plus they don't need constant tuning.
listening to you trying to explain something is like trying to wade through mud!
I decide to expend more effort on explaining things...then I read a comment like this and say the hell with it.
Love your video and I totally agree with you that Quadrajets are an excellent design. I've had small blocks, big blocks equipped with them and they always performed very well. I was taught a long ago about the does and don'ts of these carburetors you all absolutely right. They are many things that you can do to get extreme performance out of these.

Thanks for sharing your video.
Want to say thanks! I just cleaned and rebuilt mine with the help of your vids. This quadrajet was in my GMC g3500 motor home with a 454. As soon as the bowl was filled it fired right up and ran great! I will take it for a run tomorrow. It was not very dirty (compared to the ones you show) but the power piston "T" needle holder was bent and a secondary tube was dropped. Before I rebuilt It it ran real rich and stalled at lights. Float was set right so hoping that will no longer happen. I think the uneven primary needles were the problem. And the dropped secondary tube made hill climbing a pain. Also would sputter in sharp right turns. If it still gives me problems I will look at a coil. But I have a feeling this was the issue. Keep up the good work. Thanks again.
Tyler I put a carb of a 307 on a 403. What do I have to do to make it run right? Where do I get bigger secondary jets? Do I have to? The carbs actually made out of a bunch of different junk yard carbs. Maybe I should just get another carb. It’s in a 57 buick. I think there’s a video of it on my channel if you want to see.
Nice work. I'm a little older and come from the Quadrajet era. I have heard everything there is to hear about QJ's over the years. I know from experience they are excellent when working properly. My first experience was with my friends 1969 Chevy Impala. We were 15 in 1974 and this car was a rocket. We of course, flipped the air cleaner cover up side down and engaged the secondaries OFTEN. What fun. Then there are the horror stories and I was sucked in as well. Getting stuck with someone else carburetor misgiving is a NiGhTmArE...Now I have one on a 1920 Hudson roadster I built and LOVE IT. It's my FIRST CHOICE, go to carb especially for GM engines. Love the spread bore efficiency. Great fuel economy if you can keep your foot out of it. Yet, if you cant keep your foot out of it, what FUN. Mine came off of a 1980 Cadillac Fleetwood with a 368 big block. All I had to do was put a little bigger rods in the secondaries and readjust the front jets and idle. Unless your at the track, don't screw with your QJ. Even then, QJs work well there too. Thanks for the great vids. I've reacquainted myself with QJ info... By the way Tyler, you're about the best overall QJ guy I could find on the internet.
I like a slight bog lol run it up.in rpms a lol bit then jump.in it kicks like.a.mule adjust the air doors with the spring so they don't bounce lol but I like the kick feeling and not the no feeling at all between the primaries and secondary
I've been preaching Q-jet to the Holley and Edelbrock sheep since i was a teenager... I learned to appreciate them early on and made more than a coin or two on tuning them and on wagers that i could make HP with them.. I have been known to tune them right out on the water in Marine applications.. don't ask how many times I've dropped that hangar screw down in a bilge.. added a nice supply of them to my metering rod, jet and spring kit... air horn removal on a choppy lake is no fun either.. but I'm not gonna let an innocent q-jet get trashed over a bad tune or at the hands of a cam swap king.. Hands down the best marine and street carb ever.. and I'd say strip also since i've made 600 HP+ with them on several engines.. I still find one on the bench occasionally.. right next to the injector flow bench..
Had 84 Z28 with feed back quadrajet. Would start every time and ran perfect.
I really enjoy your quadrajet videos you have alot of good info. I used to think I hated them but after I picked one up for my 72 impala and had it rebuilt by a local quadrajet tuning mechanic I actually found it to be quite impressive and probably will never go back to an edelbrock. The quadrajet jet just runs so much better than the 1406 edelbrock that I had. And you definately make good points about people trying to so called "performance" mod them in the back yard cause all the dampeners and control rods wouldn't be there if they weren't absolutely necessary for the proper operation of the carb. Theyvare great carbs thanks for the videos
Man I really appreciate you making this video man. I was considering getting a edlebrock for my 307 cuz I was under the impression that quads wernt the best, but youve made great since in explaining why they ARE good carbs. Now Ill rebuild mine this summer and put it right back on my car... Thanks!!!
Great video, glad I found your channel. Plan to rebuild the Qjet on my 78 Silverado. 400 beneath it is a bit built, but the poor girl has been sitting way to much. Looking forward to bingeing on more of your videos
Appreciate the info. I've always been standoffish to the Q-Jets and believe I've even made that air door spring tension "tech-tip" in my youth on the advice of others.
I have educated myself on Holleys over the years because that's what I was using on the old cars then. Well, today I have a LeMans and we're swapping out the 350 for a 400 and I have been given an unmolested Q-Jet for it and I'm poor so that's what i'm working with so I need to learn something new now.
I found your video in my quest for this knowledge and you made some spectacular safety points that it has in it's advantage concerning the accel pump and bowl gasket leaks, both of which I know well enough.
I appreciate your sharing these point as well as the other many design improvements it has for me.
I can hardly wait to get familiar with them now!
(and toss that old thinking!)
Thanks, I think you will enjoy it. They are a very low-maintenance unit after a good rebuild.
Thank you for this video; I have a Quadrajet on the 1986 GMC truck. I have been patient to gather information before touching it because i have some low rmp bog. Doesn't create too much problem because i drive her mellow, but i do enjoy helping machines work properly and still not sure what she needs. I am delighted you mentioned the dampener, i was JUST wondering what that was :)
You're welcome. A bog isn't normal. You'll be pleased with it's performance once the bugs are ironed out.
Your videos are the best! Thanks alot for taking the time to make these videos and helping people out! WIsh there was an email to contact you-but then again, it would be a full time job answering alot of emails all day! Im trying to respond to a reply you sent to my question-about metal shavings found in the inline fuel filter...........
I raced dirt track 10 years ago and won a championship with a quad built by a old timer. Here i am now building another car but the old timer is gone, so it on me. My newer quad doesn't have the air door dampener. you think it will be be fine or should i try to source one. i should be turning around 6000rpm or more with around 350hp with a high rpm cam.
BTW, I wonder about the 5 dummies who gave a thumbs down. WTH is there not to like. If you have a Quadrajet, Tyler's videos are a MUST.... Otherwise you MUST be in the wrong place. So, to those five dummies, "I fart in your general direction!"
+BooBooJonez Lol thanks for the encouragement.
+WhoSaidTyler good video.
primary metering rods (a-b)
a=single taper
b=double taper emissions rod
same thing on secondary side.
the make different accelerator pump stems power valve springs needle and seats
big block CARB's have different size air bleeds. emulsion tubes etc.
small block CARB's do good on a big block up to 3300-rpm app
big block CARB's on a small block -not so great.
Q-JET'S are fine CARB's until warped etc from over tightening etc
don't use gasket stack's.
heated air and manifold help emissions, drivability, distribution, economy, etc
keep up the good work
TAKE CARE.
John Hutsenpiller
Thank you for the good info
+WhoSaidTyler on the primary side they make
A-rods=single taper/performance
B-rods=double taper/emissions
same on secondary metering rods
single taper -perfomance
double taper=emission.
the dampers have a metering hole to determine how fast the secondary air door opens
there a great Carb!!!
copied to some extent by Carter/Holley Etc.
you don't copy junk.
Quadrajet's are timeless
A TRULY GREAT CARB !!!
NEVER USE A BRASS FLOAT.
there not as buoyant.
I learned that the hard way back in 1985.
a stock float is fine.
THANKS FOR GIVING QUADRAJET'S
THE RESPECT GT THEY DESERVE
TAKE CARE.
I have a 383 with an AVS2 Edelbrock carb . I can adjust the rear door flap so I tightened it up so that it wouldn't open . Right away I noticed way better gas mileage . power is addictive and youll always wanna hold the throttle so the rpm opens the carb and pulls you back in your seat . But if your just cruising you make that flap much harder to open so it doesn't get into the power as quick and it really makes a huge difference . I had a quadrajet for like 10 years , loved that carb and I can see now how great it really was . Those tiny primaries would give awesome cruising torque and mileage . And the roar of the massive secondary's opening was awesome . It would be cool to see what my old carb and edelbrock performer would do on this engine . I think the engine would run out of breath to early for the cylinder heads im running now .
The vacuum secondary on a Holley gives variable cfm. It runs off Venturi vacuum, not manifold vacuum. As airflow through the primaries goes up, it opens the secondaries to balance the spring tension in the vacuum pot. Once the engine is flowing all the air it wants, the secondaries stop opening.
First carb I rebuilt was the QJ on my '67 Chevy,about,oh,10 years ago. People thought I was nuts,and would never get it running again. It wasn't hard,I dunno what the fuss is about. The car has been running fine (even better!) ever since.
It's been a great carb,and has no issues feeding the 327 under it.
The choke can be a bit fiddly to adjust,but once it's fiddled right,it's generally fine,in December with snow on the ground,or July,when it's over 100 degrees.
How does this carb do for off-roading?
Can you do a video on a rebuild and adjusting the choke?
If so offroadigans will do a shout out for you bud 🤘
Thanks, I'm going to do another rebuild soon.
If you could in the video explain to your knowledge how well it does off-roading I’ve herd threw the grape vine it’s one of the best for off-roading but you seem to really know your Shit so hearing it from you would really help me make up my mind on whats going on the ramcharger my eddlebrock does ok but I fucked with the secondaries and I want something better
What I mean is I had to do few mods to it so it would stop sputtering and dieng while going on obstacles
Thank you, thank you, thank you!
that was all kinds of enjoyable to watch!
You sir are a gem! You got a subscribe from me!
Although your video was posted quite some time ago it has been very helpful
Very good info I've heard so many people talk crap about these but my obb always runs better with the original carb I've had big dollar Holly's on it and on the street it's a finicky/ leaky carb that's not a good start in the cold with a full race valve train but the old quadrajet always starts cold and I don't have to baby sit a cold engine with it. Great video I learned more about this awesome carburetor!
My 1985 SS MONTE CARLO ran great with that carburetor
Thanks for sharing your information on Quadrajets, I've always been fascinated by carburetors and my friends would always tell me Q-Jets were junk, I always believe they were an awesome factory carb. My uncle has been trusting them for years and I guess I just lived on knowing they are awesome.
The first car I owned was a 1984 Pontiac Bonneville. Chevrolet 305cid, 4bbl Rochester Q-Jet E4ME. I rebuilt that carb when I got the car, having never touched anything bigger than a lawn mower carb in my life, and I ran that car for 10 years without any problems. I know the guy who owns it now, and it's still running the same carb. No issues whatsoever. I'm not hating on holley or edelbrock, if you like them, more power to you, but I'll run a Q-Jet before I run anything else if I have any choice in the matter. Excellent video!
(BTW, I have a 1982 Chevy C10 Silverado now with the 305 and a 4bbl Q-Jet, and runs just as good as my old pontiac did.)
Tyler
Love your videos, very helpful.
I do have a question though. You talk a lot in this video about the secondary air doors being too loose and people having thin needles causing that notorious bog. My question, (maybe I'm not thinking correctly) if the doors are to tight and/or the needles are to fat it would starve for fuel.....correct? Reason I ask is
I have a c20 suburban with a 454, 800cfm qjet and it starts to crack and pop when I open the 4 barrel, especially I colder weather. Freshly rebuilt motor (timed correctly) and carb.
Love your videos I’ve been watching since I was 18 now I’m 24 I’ve learned a lot about quadrajets I wonder why people trash talk them
I love my mechanical secondary quick fuel
Definitely keeping my Quadrajet on my 403 old's Toronado now after watching this.
People don't know how to tune them and most are old. So the pump plunger is dry rotted. They smash foot to the floor and car falls on its face.
So instead of getting a rebuild kit and a float for 20 bucks they say Q jets suck lol 😂. I agree with you, it's definitely the most idiot proof carburetor you can get. I laugh when people go buy a 750 holley because they had a 750 Q-jet. It runs, but they are losing a ton of power and running fat.
The "thing a ma jiggy" is the Idle Pickup Tubes. Is there a way to remove them for cleaning or just shoot some carb cleaner into them?
Im also thinking the metal shavings may have come from a metal tube brake line that I used as a fuel line going from the fuel pump, going up the engine block ( behind the water pump) and then the pipe turns toward the carburetor where I have an in line filter. Im taking a guess but maybe there was some metal shavings in the metal tubing from when I cut it to fit into place. I cant think of anything else that would make sense. And no-I didnt clean the tube before installing it! Crap!
where do i plumb my pcv breather valve to ? I have plumbed it to the large port beside the fuel intake rh side on the stuby pipe hanging out there.
Andrew
yes they r a great carb i've rebiult many of them most of all is the mpg u get with these carbs I never had a problem unless someone before me got a hold of it or it sat a long time so time for a freshing up
Just bought a 455 olds bored out with the Quadrajet, also just rebuilt it, getting ready to install tomorrow, but did notice where fuel line goes into the front, the threads are stripped😒, any suggestions on this fix, or do I need to buy a new part?
I believe there is a repair kit for this sold online. If they are really bad, you can resort to an epoxy repair such as JB weld, but do so at your own risk. That will also require using an external filter. Remember that there is a nylon gasket that goes over the fitting to seal it. Lots of times these strip because people neglect that item and keep cranking down on it.
this is why i watch your vids Tyler, because you are one of very few that are NOT an asshat about this stuff...lol!
What's the best solvent these days to soak in?
I use Berryman's, although it is weak compared to the old formula. Plan to leave it in a few days.
Hello, I learned a lot from your vids, question: what causes the Rochester quad 4 barrel to flood and smoke after rebuild?
+Juday Hajri (الشيخ جديع خالد الهاجري) usually 3 possibilities: the choke isn't opening, the float is set too high, or the inlet needle isn't shutting the fuel flow off because of dirt or debris on it.
I've also seen bent metering rods to the secondaries cause flooding.
I have a qjet with a pontiac fuel inlet on a Chevy 350 engine and the hard fuel line is screwed up and cut off and a rubber hose is ran to the pump. How would you recommend remedying this?
Make up a new hard line with a bender and flaring tool. It's just steel tubing.
@@TylersNeighborhoodGarage had to get a right angle inlet banjo adapter and then bought a stock corvette carb to pump fuel line. About $25 each part. The straight inlets were made for pontiac/buick engines and the right angle inlets were for chevy/GM. Chevy GM have the thermostat housing right in front of the carburator but with pontiac it was off to the side, so it's difficult to service the fuel line if you have a pontiac qjet on chevy sbc and it also heats up the fuel line being right up against it. It was all bent up and chewed up from people formed owner or mechanic. Looks clean now.
I need to rebuild a q jet for my 77 L82 man trans. I have seen and saved all your previous vids for rebuilds. I have a kit but don't think it's the same full kit I would like to use. Do you have a kit recommendation? I may need to message you later for more questions if ok. Thanks Tyler
Can you do a video on a properly working Rochester which shows the secondaries opening correctly? I heard you say the secondary doors aren't suppose to open fully. Mine don't open fully and I thought there was a problem with the linkage located behind the electric choke which connects to the piece that stops the lower secondaries from opening. I think Ive watched all your videos and cant find a video which shows how the linkage behind the electric choke is suppose to be connected. I think my secondaries don't open because the linkage isn't releasing the lower seondaries from opening and therefore, the upper secondaries wont open
i have a 78 chevy silverado sb pu 350 v8 ,it has all stock ,but i have a edelbrock performer intake nd thinking of installing it but i was wondering should i just replace the q-jet nd put a edelbrock carb with 600cfm on the edelbrock intake or just rebuilding the q-jet nd put on e intake ?
Your truck is the same as mine, and the engine under WHATEVER intake and carb you put on is still a low-compression, 165hp slug. Not saying that to be mean but it's the truth for both of us.
Unless you install an engine with much better heads and cam, or build that one I wouldn't waste time on a carb swap. My 350 runs extremely reliably with it's rebuilt factory Qjet.
To expand on the other comment...that engine has 882 heads, which have huge combustion chambers and a cam that runs out of breath at about 3900 rpm. It's perfect for a truck. Putting an intake on it will give you more imaginary horsepower than real ones. If you want it to run, strip it to the shortblock and start over. Vortec heads, good matching cam and your choice of intake and carb.
I have one of these Qwad 4's on my 1985 Pontiac 305 it is original and works perfect . I like it ! But do not take it to a service station that dose not know what they are doing . You are just going to have to do your homework and know that you are leaving your car with someone who knows . Don't be stupid when you come back to pick it up and pay for it you just mite be GOING TO COURT !!! ~ hard life (MULDEW) ~ gary b *
I've got a 87 Oldsmobile cutlass 4 door 307 motor with a quad.when it get up to 70 mph & i try to go faster it seems to loose power is that normal?
That's a little slow for a 307...but not much.
I know there was a vid like this out there thanks
I'm a big QuadraJet fan they are very tunable things that will work on any engine from 229 v6 to 500 Cadillac v8s I wish more people liked them but at the same time it's fun after beating someone in a small town backroad race getting to say you've just been beat by a QuadraJet.
Hey Tyler, Great videos. I'm getting ready to watch your videos on the rebuild of the Qjet. Looking forward to running it on a LQ4 just for kicks. Loved the sound of these when I was younger. Keep up the good work. Any suggestions just in case or where you get parts?
I keep several cores for parts but otherwise I just buy good quality kits off the internet, no specific place.
I just found a quadrajet in y shed dont know what it was doin with the ford parts i have. Anyway, it has a lever swing that locks the big plates from moving when the carb is tilted toward the big plates side and doesn't allow for wide open throttle.
Why is that?
The carb i have has has the rat tail coming out sideways towards the choke side and manual choke looks like because it doesn't have that black piece and the older looking black piece.
Never mind, i found your video 👍
The lever that blocks the plates is operated by the choke. When the choke is engaged(cold engine), it prevents the secondaries from opening and potentially causing a backfire. If you provide the numbers stamped vertically on the left side I can tell you what it came on.
Tyler what state are you in?
TN
i have had many many edelbrocks even a few hollies and nothing i do mean nothing beats my computer control quadrajet have on the 350 i have now ........we switched it over from the 305 it was originally used on........ no issues at all great performance and fuel economy that no after market carb i ve found yet can match............ who needs efi right lol
very cool.
I have a 305 in a 89caprice...when i turn corners sharp it burns a little rubber but the whole car shuts off then comes back on..maybe battery or carb?? Let me know thanks
fuel tank?
It does have a dent in the tank
I really like your 2 videos about the Quadrajet. There is a company called Garanteed Carburetor. They sell rebuilt carbs and one of them is the Quadrajet. I have a Chevy 454 V8 in a 27ft Winnebago. It is a 1989 motorhome. The vehicle has 98k miles on it. The price of the carb is 265.00....any advice? It is a California vehicle but I don't live there anymore. David 🐈
so you can change your secondary mixture ( Wide open dyno testing) without tearing the carb down? NICE! ...just bought a 750 quadrabog today for 20 bucks, watching this shit to see what i got myself into ....So...is the "bog" a lean bog, or rich bog....thanks.
It's a combination of both. The air doors act directly on the secondary rods, and also affect the secondary pullover enrichment system. When the airdoor tension adjustment gets screwed up by a well-meaning but un-informed person, the airdoors slam open, bounce back nearly closed, slam nearly open again, repeat. So, the airflow and fuel metering is all over the place while the secondary throttle blades are hanging there wide open the entire time.
Rochester designed the airdoor tension operation and airdoor damper for a reason and it wasn't to restrict performance. Guys can lecture on Holley vacuum secondary operation all day long but they can't figure this simple system out. Thanks for watching!
so this "bog" is really just a combination of lean and rich then...that can be fixed by a correct actuation of the air flap...i was under the impression the "bog" is either a lean condition or rich condition, not a combination...tell me if i'm wrong...thanks. I just started watching your first video now , after i posted this. Thanks.
@whosaidtyler i need educated on chokes thats on my carb, my boat has a 305 chevy low block and no im not a mechanic ,but willing to learn and im having trouble , im told im messing a linkage on the choke , so my question can i get a kit to replace the choke , please help me
I need some more info:
1. The carb # which is located on the port side of the carburetor, running vertically behind the throttle linkage. It's stamped, not raised letters.
2. Is it electric or hot air choke
3. What problems are you having?
Thanks.
once i get back out on the boat i will send pics and alot better info
@ who said Tyler I have a 87 Caprice with a 305 motor and when I go up to 45 miles per hour it surge what could cause this to happen with my car I change the fuel pump spark plugs wires and still the same problem
+Dequan Vales See if there are trouble codes stored in the computer and go from there.
lean surge is APT adjustment is off.
turn screw counter-clockwise app 1/8 to1/2 turn.
I agree 100% .
Works awesome that 454 hauls ass now!
Sweet!
you my good man helped me out. I can give the edelbrock carb back and just find a Quadrajet with out the stupid electric components. I have an 86 gmc g2500 and the stupid air fuel control solenoid I want to get rid of.
That's not an air/fuel solenoid. It's a dual capacity accelerator pump. If you leave it unplugged works just like any other qjet. It's a good 800cfm carb. 3/4-ton trucks did not have the same electronic controls and emission controls as cars and light duty trucks.
i kept it unplugged and its not running any good with or with out it plugged. If i full throttle it it bogs bad like its starving for fuel but i have replaced everything from filters to fuel pump. When it idles it smell as ifnits pumping to much gas. When i look up the part to see how much they cost they called it a mixture control solenoid. Im at a loss with it.
im watching your computer controlled quadrajet video ( Understanding computer-controlled Quadrajets part 1 of 3 ) you start talking about it at video mark 10:23. that's the part im having trouble with.
Any chance I might be able to get an email or chat about switching from an electric QuadraJet to a non computerized one?
Aaron Silvious Sure. If you go to my channel page and click on the "about" button, it should give you an option to send me a pm. Let me know what you are planning and I'll advise you.
WhoSaidTyler it doesn't give me that option, only shows your followers and videos, etc. My email is aaronsilvious@gmail.com and it's not spam, scout's honor
Years ago I got an engine trans unit out of a motor home. today after watching the decoding video I decided to go get the carb and see if it was the original to the 454 chevy engine and 400 trans from the motor home. I don't think it was. 17059530; 3218 julian.
14:00 = 90% of carb issues are timing issues.
that pull off looks new
That it is.

Great videos I'm gonna watch them all, I will have one on my Cheyenne one day!
How can I make a quad work that came off a 305 from a van to a 496 BBC
You really can't. The internal calibration is way too lean for a big cube engine, plus it very well be the smaller 750 cfm version. Look for a 500 cid Cadillac Qjet as a starting point instead.
Ok Thsnks for the heads up. I was thinking of just jetting it up by looking up the specs for the 500.
Lol I have 3 carbs that cane off sbc and love to use them. But thanks for the heads up.
watching a guy on another forum explaining how much better his runs with the secondary air doors removed...of course he bought it this way, so he has no idea how it runs WITH the air doors installed
I like quadrajets but all I hear is quadra junk too bad for them can you buy the metering rods or what is the process for a 400 pontiac
You can buy any of that. Quadrajetparts.com has all of it. The Cliff Ruggles book on Qjets is a must-have.
If that's still the original carb on that 400, those are about the best of the best.
I LIKE QUADRAJETS
curious as to what serial # this carb has.
17059228, for a 1979 Corvette w/ L48 and auto trans.
I guess this one came off of a 67 oldsmobile
1979 Chevy
Joseph, the first year for Quadrajets was 1968.
@@davidcollis4758 My 67 olds 442 came from the factory with a Quadrajet✌
@@donaldgreen7471 you are correct sir. As an old school mechanic and I worked at a Corvette shop most vehicles didn't have a Q jet as standard equipment until 68. Corvettes came with a holley until 68. I stand corrected. Thank You.
Great Video again WhosaidTaylor love watching them. I've been looking for an answer to why mine floods. It stalls and then fuel spills out over the top of the Carb. At a guess this is a problem with the inlet seat. I did have a mechanic look at it some time back and he cleaned it out and gave it a 'not the best example he has seen type comment'. Am I heading down the right track.? I cut a utube video if you are interested to have a look.
