- Carburetor Rebuild Basics covers the basics of rebuilding a carburetor. Now there are a LOT of different carburetors out there so this video won't apply to all of them, but it will give you a general idea of what you would be in for if you decided to rebuild one. Me, I like rebuilding carburetors. There's something about mechanical things like carburetors that interest me. How even the smallest part has a big effect on the overall operation of your engine. Since we've gone to fuel injection carburetors have become somewhat obsolete. I'm still a fan though. I may be a little rusty on this stuff since I haven't done this in some time but I hope this video helps you just the same. If nothing else, I hope you're entertained by it.

I know this is 6 years old, but I'm commenting anyway! 😉
I MISS Carburetors!!
I'm a Retired Ford Tech, ASE Certified as a Master Tech in Carburetion and Fuel Systems.
Going through these old Videos of yours is making me want to get an old Car, just to mess with.
Even going to a Auto Wrecking Yard and getting a few Carbs, just to rebuild/modify!!
Now I know you want nothing to do with that 200ci Stovepipe Engine, but back in the day we used to swap those Holleys for the Carter 1bbl off of a 300ci 6cyl Ford Truck. They're almost 100cfm larger and significantly improve torque.
Bolts right up, and all linkages fit the same!
Thanks for posting this and helping me realize that I should not rebuild my carby because it is beyond my capabilities. Good video 😀
Thank you for sharing your knowledge so freely it’s very helpful to me, now l have a Carburettor problem with my Ford Econovan I don’t understand the problem my mechanic were told me about by see this video I have learn and understood thank so much I wish you were near here I live then I would like be your customer.
Canada because she is Linda Lin....
@@nightynine4061 understandable have a great day
Thanks Eric, you've taken me back to my youth... Pulling the carb apart once every few months and giving it a good clean, as a service item. One thing that was unique about carbs was, as a car owner, you got to know your carbie (even if you didn't know what it did), but if it wasn't perfect (and rarely they were).... You still eventually learned how to start the car first time... Maybe two throttle pumps before starting... Maybe half throttle... It was always a variable that made every car unique. Nobody else will be able to make it start first go :)
As an electrical engineer (not too mechanically inclined), I really appreciate your videos Eric. You are articulate, methodical, and full of good information - Thanks!
Carburetors, I think they're fun. Carburetor Rebuild Basics (Part 1) -EricTheCarGuy
you may think that, have you thought of doing megasquirt, and go injector ? :)
you may brush the dust off the welding skills, get 4 injectors on, get a trigger sensor on.
and a MAP sensor.
off you go.
then you can convert to sequential ignition, and this 3.3 will really pull like a champ :)
also a narrowband.. almost forgot that, you can just take something off another scrap car or something :)
just as a little edit, I see why some carbs are nice, but if you want a better engine, loads of people buy a new carbed v8 whilst a I6 or V6 can pull just as good with proper electronic management and leave room for even turbocharging or compressor with correct mixtures and future build.
and it's heaps of fun to do ECU work yourself :)
you can drop me a message or something and if you wanna know anything I can help ya.
Road2Perfection MS has a huge learning curve. BTDT. Way beyond the scope of these videos.
***** didn't know he was going to swap, or planned.
my point was, alot of people buy new engines instead of putting on efi, efi increases effeciency, power, and with effeciency comes better milage.
Efi can be done in a day with a friend who knows it :)
changed my efi on a already efi'd engine, stock to standalone and that took a day including driving to another country to pick it up, solder up all wires, set settings, drive, morning to evening.
My first EFI experience, and got it all working the same day.
I personally used MaxxEcu
opened up a completely new realm of car modification and knowledge :-)
right after engines, carbs are the most fun to rebuild
I didn't find this video in your playlist for fuel and emissions; it appeared there was only a part 2. Anyway, found part 1 here, so that works. Just to let you know.
"Now know that carbutetors still have gas in then even after they're removed"
*_laughs in sat for 25 years_*
That actually looks easier than I was expecting. Just gotta STAY ORGANIZED
thank you for this, almost 10 years later! just bought my first classic jet boat, 1974 marlin with a 455 olds and holley carb. it starts and runs fine but the first thing i want to do is rebuild the carb.
i’ve rebuilt my old dirt bike and quad carburetors with my dad when i was a little kid but that was over 16 years ago and i don’t really remember much. your videos are gonna help me tons, can’t wait to get this thing apart to learn some things and maybe make a couple small mistakes haha
this was so interesting , the 30 min just flew by.. can't wait for part 2
farerse did you watch part 2 ?
I remember carb rebuilds from an earlier era. For a one barrel , those Ford carbs have a lot of fiddly bits, compared to some 2 barrels. I also liked to use a compressed air nozzle to blow out passages of dirt and gunk. Thanks for video ETCG
I love how in the beginning he's talking about trying to remember where everything goes even though he's recording it and can just go back and watch it to see. Lol
Thank you and the person behind the camera for filming this. Keep it up.
YES!!!, I'VE BEEN WAITING FOR SOME OLDER REPAIR VIDEOS. THANKS A MILLION ERIC AND KEEP UP THE AWESOME ADVISE BUDDY.
Yes! Thank you, i was just about to attempt my first carburetor rebuild and you are always so helpful. I am glad you finally got a video like this haha. I am a little concerned however, this is kind of an oddball carb. It is the stock carb off a 1979 Mustang with the 2.3L turbo and California emissions. My research into it has been helpful but it hasn't as clear as a beginner needs. Also, the car has been in storage since 1992, so i believe a rebuild is vital. I appreciate any help you can offer. Thank you again!
Thanks for the lesson. I've always wanted to learn about carburetors! Great video.
Great timing! My Bronco II does the same stall when cold thing in my driveway but once the engine is warm, no problems. Looking forward to the carb adjustment video.
man my first car was an old ford escort. had a 1 barrel carb, its been forever since I seen a rebuild video. awesome to see this tutorial eric. nice job!
Great old school rebuild, you take me back. Love your comparison with the toilet bowl . . . I can just hear a plumber doing a toilet tank rebuild video saying "see this float system . . . . it works just like a carburetor . . . ." haha . . . thanks for the great video . . . Rog
Eric: timely video. Carburetors are a lost art. I'm rebuilding a Holley 4150 double pumper, followed by an Edelbrock. Thank goodness for videos like yours. Too bad CZcams did not exist back in the late 1960's and early 1970's when I knew squat on tuning carburetors. Keep up the good work. KMan.
I'm glad you mentioned the throttle body butterfly shaft. I had a 600 cfm Holley that I rebuilt twice trying to figure out a bad idle situation. It turned out to be the worn butterfly shaft. There is a rebuild kit for the shaft, but for a little more money, I just got a brand new carb! Thank goodness both of my cars and boat motors are all fuel injected! My days of playing with carbs are over.
As a guy going into the field with little more experience than working on my own sh*tbox, I appreciate your videos like this where you really go into detail.
Thank you for taking the time to do this procedural. I'm about to tear one down myself for the first time and know i've got a leaky throttle shaft on a 2-barrel toyota corolla 4-af. So this was really helpful.
I have to wait a week to finish the episode! I'm following along with my own carb and now its in pieces!!!!
Love how you show us this. I am not mechanically inclinded whatsoever. I've learned more about carburetors than I ever have in my life. Great job! Can a beginner like myself do this to a 4 barrel carburetor?
Lots to learn from this video. You explained that dual metal choke thing really well.
Thanks Eric, i have been waiting this for so long. I hope it will help on my carb nissan sentra.
Awsome job, Eric and Brian. God bless.
Love videos like this, Of course vehicles haven't used carburetors in years but in the late 90s I owned a 1979 Dodge PowerWagon and I rebuilt the carb on that, it was fun as well.
Carbs are beautiful pieces of engineering. They are both simple and complicated at the same time.
Excellent video. Great point on the leaky shafts on Quadrajets. I have that issue with my 68 impala. I was just waiting for someone else to say it.
Very thorough video. Also, general enough to cover most carbs.
Great video, Eric. This is just fun to watch.
I am so glad I watch wrangler star (either him or sensible prepper I forget which) as I used to watch you for one of my classes and I could not remember your channel name but he recommended your channel for learning about car stuff and that makes my week
awesome topic. looking forward to part 2
Eric that was smashing mate, i also love carbs :-), we have lost so much in modern cars with computers controlling everything, back to the basics is refreshing :-))
Every young person should start with old tech, you learn how clever the designers were :-)).
Your knowledge and expertise are great to watch.
Great job Eric. Brian you deserve props for camera work!
Great vid, I like to dip in acetone before blow drying, dries easier & quicker
Great video! I love carburetors too. Something I always do is lay a white towel on my bench beforehand, so if any parts fall they don't go flying. and all the small parts you put down don't roll around.
I've been waiting for this for sooooo long!
i'm starting at my first car, thanks to People like you it's possible. thanks for sharing you're Genius mind!
no. why did it end I was so enjoying it while at work. Can't wait for part 2 Eric. I love all your vid, and this is from a guy that only know how to fix the easy issue on his own car lol.
This is honestly one of the best videos I have seen on carbs. They really don't teach you too much about these babys any more and its a real shame, its too interesting to me not to learn about them hahah
very cool, as always i still learn at least one thing every time you shoot a video on a subject i feel is minor or very common. Seriously eric the cool guy
Can't wait for part 2
Thanks
Been waiting for this one ever since you got the Fairmont... YAY \o/
Eric is the professor of carburetors. Great video.
Hi Eric,i have reconditioned loads of Carbs, I didn't see many jets in there, UK ones have main jets and slow running jets etc, nice to take them out and blow through them, and through the passages...nice video cheers from England...
Hi Eric, Great job! Brings back memories of my 79 and 68. The 68 had the float issue you described and ran perfect till you made a left....then the high fuel level spilled over and nearly got me killed in traffic. Figured it out very quick after that:-0)
a speck no bigger than the size of a speck of pepper on top of the float needle will cause all sorts of bad crap. Primarily float over filling. Finding something like that as the root cause of a problem is a pain but well rewarding.
A lot of the same methods followed here when I rebuild any kind of carb. Lot's of good info here.
We waiting 😄😊😃😍!!
Part 2 !!
Very informing vid eric, thanks!
Just as i have been getting carby problems. Cheers for the info
I think your "done with the world" facial expressions are the best!!
I'll wait for Part 2 !! Quickly
Thanks it's nice learning here. Do more Pls Eric The Car Guy. Its good for diy..
Very good idea to label things with tape or whatever.I color matched my in and return fuel lines with electrical tape when I had to drop my tank. But another thing is use your smart phone, take a photo or two then you have a pic of what it looked like before.
I can't say I didn't enjoy this video. Really interesting and now I'm finding myself thinking about ripping off an old GM carb just to practice rebuilding them.
Ah how the memories come flooding (is that a carb pun?) back! That choke was the bane of my existence.. The exhaust gas would eat away at the little fingers on the end of the choke plate axle that engaged the spring, and sooner or later the little fingers would break off and the choke would no longer work. And, of course, that was something that was NOT included in the rebuild kit. So, every couple of years you just got used to replacing the water pump and the carb. Fortunately neither part was very expensive nor very difficult to replace.
Hey Eric, great vid as usual. If you ever happen to do some rear brake work on some mazdas I would love to see it. Did my rear brakes tonight on my 03 protege5 and the caliper pistons are pushed back by using an allen key. I also had to remove the parking brake bracket that was held on by a rust-welded 14mm bolt. I used your heat trick and it came off right away. Thanks again.
Thank you for the video. I can remember well rebuilding carburetors including a carburetor per cylinder engine that had a habit of on cold days freezing's such that you lifted the foot off the accelerator and NOTHING happened. At the time the conventional wisdom was to run the in take via the radiator BUT that would affect volumetric efficiency so I never did. I just gave the throttle a kick in the hope of cracking the ice off. I was lucky no accidents. I love fuel injection systems now but still hate the crappy carb on my GMC generator :-)
Great video man hope someday I have your skills Id love to fix cars for a living my dreams job
good vid. i'm probably gonna have to mess with the carb a bit to get my 110cc chopper engine going. hopefully thats all it needs, wiring looks like enough is there, has good compression. seems much better than the rest of the bike...
Great video. I have a carb off of my Toyota 22R that I've been holding off on rebuilding. I replaced it with a Weber for the time being since it was cheaper than the rebuild kit with the new floats. I think, after watching this, I'll give it a try.
the same for me ! and i can tell you that i love LC engenering :)
Nice video!
Hail up Eric I am now seeing this your the boss bro I am one of your biggest fan this carb is almost the same with a Toyota aisin type for the 5a engine.
Seems to me rebuilding a 30 year or so carb would be a no brainer but I know you have other plans for this car. Looking forward to the adjustment part. Mixture !!! Just did my 67 MGB with a weber. Looked new but fixed a lot of issues. THANKS!!

Amazing what this man can do with Stanley and Harbor freight screwdrivers and 2 adjustible wrenches. No expensive Snap-on , Mac, Matco and other super expensive tools. He relies mostly on his knowledge and wisdom " take pics" , also his enthusiasm plays a big part on his success. I messed up , didn't do what he's advocating. I wish l had seen this video before l started messing with my carb. Now l have a disaster, springs all over my garage and my little balls are now smaller.
Chrysler liked to use brass floats on some of their fuel sending unit floats in the 70's.. Seemed like just about every one of them developed a hole and would not longer float. Getting that tank out sucked... Eric, great video, Im glad someone finds carbs fun, I remember the Holley 1920 SB being pretty darn reliable but not all were that way!
Hey eric!! My friend has exactly the same carb ih his maverick that Im helping him to fix.
This video is extremely helpful!
But one question if I may... What is the number of the rebuild kit?
Thanks Eric!
Very cool man, I did the same with a motorcraft double barrel
What do you think about ultrasonic cleaning methods?
+EricTheCarGuy I just found an 82 Fairmont for $500.00, and the only problem is that it's carburetor needs to be redone! Funny enough I was watching this video earlier. Thanks, this will come in handy!
I've found that some of the older foam/neoprene floats can also expand and cause the float to drag on the walls of the bowl or even get stuck (at least in the case of GM quadrajets). I've heard some people suggest that the ethanol in the fuels these days is really tough on the foam floats.
good ol carbpataters
Oh goodness, I haven't heard that one in forever. Thank you so much for that laugh. Props, dude.

Liam Herman Sorry, man, PMM nailed it right on the head. It's gonna be hard topping his.

Wow. Haven't rebuilt one yet. Didn't realize how many parts there are. Kind of an automotive cuckoo clock. Lots of stuff. Thanks for making the video 2.5 years ago.
I’m about to rebuild my 78’ Honda CVCC carburetor on my own. I’ve never done a rebuild nor do I really understand what everything does but I am going to attempt it.. as long as i keep my GoPro recording on my head throughout the whole thing i should be fine.. maybe.. lol
I've got an 86 Nissan 720 & I'm gonna attempt to rebuild the carburetor (Hitachi I think) 😬 nice video!
Thank you very much!
Wow, you are a zen master!
I watch carburetor rebuild and I have a toyota paseo electronic fuel injection. Seems legit. (I like Eric's videos ;)

Hey Eric, can you possibly tell us what is the solution you used for the Carb dip? I am curious to know as I am wanting to rebuild my Q-Jet.
Love carburetors over fuel injectors any day.
but why

'Your carburetor is like a toilet.' That made me laugh. :D
Great video. I only know EFI, so this is very educational.
Hi Eric. I really like your videos. They have been a big help to me. I don't know much about mechanics, but I am learning. I have 2, 2 barrel Rochester carburetors. I am going to rebuilt both and put one of them on a 307 small block that came out of a 1968 Camaro. Anyway the bores in each carburetors are different sizes. One carb is bigger than the other by about 1/4" in Diameter. Is there a differents as far as better fuel consumption or power with the bore size? Thanks. Andy
Name of the solution?
"your carburetor is like a toilet" -Eric TheCarGuy
You're the man champ
thanks for sharing ...
My first car was a '78 2-door Fairmont...200 motors are super tough... and the c-4 transmission can handle quite a bit of abuse too...
I would suggest that prior to the actual rebuild, that folks use spray carb cleaner and its tube to blow all ports backwards and forward to be sure there is not a internal blockage. The spray itself will give a good visual that the passages within the bodies are open. Eye protection is a must.
I never thought I would be buying a car with a carburetor, but then I discovered what a great car this 1989 Civic is... It runs well but I can't stand not knowing the magic behind things. So here I am.
We younger people that have only driven on fuel injection vehicles, we used to ask to older mechanics if carburetors were good or if they re happy that carburetor is gone.
Most say that carburetors were good and they like them. Here in Brazil we ve the option of having ethanol/methanol fuel, but on the carbureted times, specially on winter that can get cold here on the southern part of the country, it was pretty hard to start a carbureted alcohol (methanol or ethanol), vehicle. It had a small gas reservoir to spray some gas on the intake manifold to help to start those vehicles on cold weather. But they are good, and motorcycles still have them.
Instead of rebuilding my leaky carb on my Subaru, I put on a weber 32/36 DGAV. There is only 1 vaccuum line instead of 300 (it is not connected now though because the distributor diaphragm leaks) and it is easy to adjust. Both power and economy are better now and the mechanical secondary works a lot better than the old vaccuum operated one.
***** Flat engine, EA81
What's the difference between a nirmal carb and a weber carb?
Moving Up Diy
They are an old style, simple carb. A larger Weber carb can be used to replace a smaller stock carb for better performance, or they can replace a modern (80s and 90s) carb that has a lot of emissions gear on it.
They also have a range of high performance carbs that are a popular modification for Japanese and European cars.
There also were a lot of cars that came stock with Weber carbs.
Is there a proper disassembly and reassembly process for a carb? Or can I just start unscrewing things and it will work.
Have U clean internal tubes on carburetor body? Sometimes a particle of dirt stay inside it. May be U use some small pump for it?
Hey Eric. Seeing your carb was missing a check ball, would that be the reason your car would not start good in the morning?? All your gas ran back.
Too bad you didn't put this video out a few days earlier. Just took apart my first carburetor yesterday. It was off of a yahama xs400 bike I picked up last week. Anyways, good video!
