Hello I just put a new carburetor kit in my quadrajet and for some reason I lost vacuum on the tube that pulls vacuum for the timing? What if I used the wrong gasket on the top side would that cause it to happen? Thanks Sir

Good video but please eat your food before doing video 🤮

Tolerance for a warped quadrajet, I have semi straightened it out but still have a 1-2mm gap from the centre to the secondary side where the 2 big screws go into the body. Base plate is also flat. I was thinking about making a set of gaskets to replicate and give myself another half a mm of tolerance or so on top of my new gaskets? Thoughts from anyone who sees this

Buy yourself a pair of flush nip cutters from dorman, Titan or Klein and you'll love them for stuff like this

Great video! Love it, always wondered about this APT thing

Does the APT system also affect the idle mixture screws? Could it be that if my idle is too rich (AFR of 12) that I would also need to turn down the APT screw in order to get the Idle Mixture screws effective?

Well done.straight to the point with the carb on the bench. Din’t have to fight with camera and mirror’s to show where screws were located..

pre sure power vavle acc pump few the vcum items and hoses had cruse set up all them bells now rather just pull it cap off lot stock for now less vacum just go old 2barrel basic

1983 march april 1983 g30 cutway rv 5.7 350 was mouse house haveing fun fix it got it run pop off etc no pedal idle yep geting them kits parts plan just get e-pump added newer block fuel pump still waiting get primp 43gallons half full that old gas had air cover so mustly just norm wear able parts

The rod end is so short and the fit is a little loose so it does not stay on. Thirty tries later and it keeps falling off during this process. Bad design.

Outstanding video by an expert.

I tried emailing you guys the other day about a carb and did not get a response

I have an early 70s QuadraJet with the divorce choke... want to change intake manifold, but keep the same carburetor. Is there a way to do this?

Thanks for the information!!

awesome videos

Are the nails the secret to carburetor repair? I'm willing to learn.

I bought some parts from you in the past thanks for keeping these old carbs alive

Very helpful Sir! The instructions that came with mine were pretty vague on how to set the choke 👍👍

Great info, i resolved my issue by restricting the idle bypass hole air my mild BBC. The bypass holes were too big for my application, causing the idle mixtures not to respond very well at idle.

Made rebuilding my carb easy! Thanks!

Great video and I was wondering where you might know a site for an 1987 4 bl electric choke housing because my 3 housing screws were so tight they broke the crew hole casings off getting them loose?

ok.... what if i don't have an apt at that location?

Thanks for the info!!

The electric choke elament needs to be powered thru oil pressure switch.

I'm not sure what kit I need. I think it already has eletric chock but the choke flap stays open so I'm thinking replace everything.

What jetting, primary and secondary’s do I need for my 87 caprice classic quadrajet for here in TX? Was rebuilt and jetted for Colorado altitude so I need to change that. Any and all advice will be extremely appreciated

Great video!! I'm running a 350 with 2.02 , 1.60 valves and a bigger cam and have been having issues with idle. I'm pulling about 17 inches of vacuum at idle do you think I need bigger idle tubes? Or is this enough vacuum to make the stock ones work properly?

Great instructional video... I really wish my father was alive to see how easy really is to do something we tried to do together but never really worked right.. again thank you..

How do yo cap tube from exhaust manifold that carried hot air to choke?

Good info! Thanks

Great videos. Can You explain fuel circuit, how it is controlled when on idle what is holding the fuel from part throttle and secondary fuel cuirciut from flooding the engine, can You explain what is triggering part throttle system to get in and same for secondaries. Air flaps and linkeages are visible but ilustration what is happening with fuel i think can be interesting and big step for understanding.

thank you that was what i needed for my 85 trans am to pass the emissions test in Colorado

thanks for the vid, my rod fell off too!

Have you worked on the secondaries accelerator system it helps take off. Some of the Qjets upper secondaries butterflies are slotted in front of the port to get higher vac signal sooner for more fuel. I normally drill them just shy of a wd40 straw anymore that that will be too rich.

Do these adjustments work the other way too? I had to adjust my choke thermostat clocking and vacuum pull off a while ago, and ever since then, my fast idle is really high and stays there for a very long time (5 mins or so before finally dropping down a bit). Is it possible that, by making these adjustments, I tightened up the fast idle cam?

Hi thank you for the great video. I see on your website I have to plug in my code on my quadrajet carburetor. I have a 17085213. Will the QB1 work for that?

good idea about position your camera in a different area so we can see what you're doing

I found a beautiful way to fix the Frozen and broken lower older apt that gets never adjusted because it's froze

cool!

With these carbs getting harder to find, this will save a piece that would have been scrapped years ago.

My only problem is doing a second gear WOT pull. The car sucks the bowl dry. Having to run a 3 nipple jeep fuel filter to prevent vapor lock. Would a 3 nipple hi volume mechanical fuel pump fix this???

Great idea. I'll be doing an early one in the next few months. Will be ordering everything from you.

So cool,thanks very nice!!

Great repair! Love these videos, keep em coming!

Genius!

I have a quadrajet rochester carburetor on my 327 small block chevy I ended up ordering a used carburetor off ebay and all numbers match. I watched Your video when I install this choke lever and and get it set up do I need to install a hose on passenger side of carburetor to operate the choke or how does that work

Between Ruggles book and your videos I am starting to understand how it works and how to fix my problem in the going off idle circuit. I have to richen up the idle circuit. My tubes are stuck pretty tight. I have to try to get them out again or try to drill them from the top and flush out any chips.

You have helped me to understand how to fix my problem. As soon as I go off idle with light throttle it falls on its face. I have had trouble getting out the tubes, even with heat. I am going to try again. If I just punch it and not on a hill it seems to bypass the intermediate circuit and go directly to the main circuit. It used to be extremely smooth until I put in another cam. If you have a flat tappet cam and have had failures go to diamond like coating (DLC) lifters and it all stops.

Can I swap the base from a electronic carb over to a non electronic so I can gain the use of the the TV cable mount? Without having a bunch of headaches?

I have a Camaro Z28 - 1984 - Trans. manual. T5 Question: When choosing a new and same Quadrajet 4BB carburetor, is it important to know if it is for a trans. auto. or manual??
