One of the most important parts of a carburetor rebuild is setting it up properly after you're done. There are also many times where a rebuild may not be necessary and you just need to perform some of these adjustments. Either way, I hope this video will help you should you need to adjust your carburetor.

Thank you SO much! My mechanic swore I needed a new carb, but all I really needed to do was make a couple simple adjustments. I think I still have a vacum leak somewhere, but this alone has saved me over $400 on a new carb! THANK YOU!
Most the time the mechanics just don’t feel like working on them lol
I love how people take the time and make videos on how it works and repair automobiles. THANKS FOR THE VID. YOU ROCK!
I was in a world of chasing my tail trying to tune my carb until I watched this video....then I was able to nail it. Thanks Eric!! What the internet does best. Subscribed.
Another great video Eric thanks. Folks like me would still be paying through the nose and suffering vehicle availability loss while waiting for a busy shop to diagnose and correct things. Wonderful of you to share your invaluable experience.
I have so much respect for this man, I'm trying to be a mechanic outta high school
Vendetta how’s it going?
I’m trying to get into one of these trades after hs also, I got auto body repair and pain refinishing, teacher got a old v8 Camaro in the shop
I asked too work on it and was aloud, first I had too turn it on... it was carbureted and man it felt fking good, then I started welding a panel onto it
Short story is it really sparked my perspective and drive for the trades
@@Mistyfgdf Just do it! Don't waste your time with a school, just get tools and go to work!
You go for it young man!!! Even tho, I do recommend going to college to study new car mechanics and diagnostics. Read some books on modern cars during your spare time if you’re not gonna go to school.
me too but my mom wants me to go to college
@@bobi_lopataru Trade school = College
You know it's an Eric the car guy video when a 'basics' video is 20 minutes long, I love it. Scotty Kimler would go over an engine rebuild in a five minute video,.
you're a god send, i've been looking for info on holley 1946 tune ups and tunes ups in general, and your video is probably the best that i've found. keep up the good work
Even today, in 2021 this video is helping me more than you know! Much respect 🙏🏼
Thanks man! Fixed my '85 ford truck with the 300 inline 6. 300000 miles and going really good.
It has one of those Carter yfa auto-choke one barrel carbs, really similar to the one in your video
thank you, i adjusted my choke like you explained and it fixed several issues i was having (with my 78 monte carlo) for months. Car runs like a champ now
Love you man! You are so helpful to us young guys trying to get our skin in the game! Thank you for sharing.
I've watched several 'how to' videos on RUclips. EricTheCarGuy is by far the best. He has a great personality, good enunciation, good sense of humor and if he had a radio show I would listen for sure.
Thank you, thank you, thank you!!! I'll feel much more comfortable rebuilding and adjusting my carburetor. My '71 Gremlin has needed this for a very long time, the rebuild and the adjustment. Also glad you used a one-barrel Ford, since it is quite similar to my Carter YF.
Thank you so much for this video. I have a motorcycle with three carbs that I just rebuilt and this is helping me find out how to properly adjust them.
Best video on carbs. No gimmicks no fancy video tricks just useful honest information.
There are so many instructions you can read and so many videos, but the little gem that makes this one so much more realistic and valuable "I don't think that's intake vacuum".
Great video! Thanks for actually showing everything as you go, instead of just talking about it. Very helpful.
Now that the carburetor has been rebuilt, let's adjust it. Carburetor Adjustment Basics -EricTheCarGuy
Very Good i love it.
Now we need an explanation for the vacuum gauge what can use for and how to read it.
Thanks alot.
toolman talal You want equal vacuum across all of the ports
+Thomas Gionet
i don't understand the partitions of the gauge how to read it and how to use it.
inHg is inches mercury, a way to measure pressure. -29.92 inHg is full vacuum, 0 is atmospheric pressure at sea level and a positive reading would equal positive pressure. To use the gauge you simply connect it to a source of vacuum.
Thomas Gionet
great explanation thanks.
I have a vacuum pump break bleeding ket and there tow units in the gauge inHg and i can't. remember the second unit and i can't figure what scale for what unit. sorry for the very much questions.
thanks again.
Loved the background of Mason. I enjoyed that trip.
This video saved me so much time and trouble with my 78 Subaru Brat. Really great job explaining! Thanks so much
Great job with the adjustment and the rebuild. Over the last couple of years I have learned a TON from your videos. Love em!! Keep em coming and stay dirty !
Just rebuilt the YFA carburetor on my Fairmont, and this is super-helpful. Going to buy a vacuum guage and tune it now...thanks!
Love it. Was a good way to learn with your step by step method. Thank you Eric From NZ.
I grew up adjusting carbs ,,,, seemed like a monthly thing . I always had pintos . Gotta love the ford . Now days autos are not so personal . I remember pulling off the highway and grabbing the screwdriver . Eric you are bringing the yesteryears back and I thank you very much .
Beautiful ride Bro !
wow! this was the best video How To for Carberators i have found! GREAT DETAIL ON FIXING CARB CHOKE AND IDLE SCREW!! THANK YOU!!
Awesome video, and it's going to help a ton when I go to adjust the Carter RBS in my Maverick this weekend.
Great video! Helpful as always. Keep up the awesome work.
Eric rocks. He will tell you stuff you never even thought about.
Great work bro. Going to try on a 1993 nissan sentra b13 Carburetor. Revs at a 1000 when in gear, once its neutral revs goes up almost 2000 rpm.
You guys are really doing an awesome job. Profuse thanks for the auto enlightenment
That tuned up strait 6 sounds great in it's own non-assuming way. I predict Eric will have trouble pulling the trigger on an engine swap...he's spent so much time and effort working on that engine and it's running like a beaut.
Very very good video! Very informative and thanks for going over all the steps.
Hey, it's the predecessor to my 1984 Ford Tempo! I need to make some adjustments on its carburetor so it only seems fitting that this is the video I ended up watching on the subject.
Eric, big old ford fan that vehicle is running perrrrrfecct, Nice Job.
Great video erick, keep it up, cheers from ontario calif.
As usual very well Explained, One of the best,
I just had an influx of memories from working on a old Buick 350 and how I had to go through 2 Quadrajet s before I could find one not dicked six ways to Sunday and then adjusting the hot air choke. I guess I got to put that engine back together
Hi Eric, in the whole video you did not mention float level check/adjustment, and I was waiting for it since in my opinion this is the first basic settings you should check/correct when adjusting any carburettor. Often the lip/tongue part of a float can be bent to set the float level just right.
Float level is important because it affects mixture richness along a very broad load range.
There should be levels of thumbs up for videos because just tapping a single thumbs up does not express this is a great video and really appreciate it
I always set idle mixture with COLORTUNE, never thought of doing it with vacuum gauge. many thanks for this hint!
Watching In Missouri A great video you did a good job explaining how and why the carburetor. Choke works
You're the best, dude. Thanks for continuing to make these.
How come those asshats at the network haven't offered you a show yet?
EricTheCarGuy Thanks for a great video. Your video helped me visualize and understand the adjustment instructions from the manual, some time ago when I started playing with cars. I hope you have more videos of classic cars in the future!
Thanks again!
My moped was running on way too little air, but after 1 hour of adjustments it ran just the way it should :)
great video and good information
Killer.. easy view of everything. Thank you!!
thanks for all coverage ..
first of all this is first time I saw you drive :)
second I saw your workshop from outside :)
finally first time saw your sunglasses :)
have fun be safe and stay dirty :)
with Regards ..... best follower
Like his videos. He's thorough .
Thank you for your vids, sir.
Damn that winding out of second was nice . I can't wait to find a pinto again
This is such a good video. Thank you
I think you should re-do the 1/4-mile baseline time, now that she's running so well. I'll bet you can crack 20 seconds. :-)
Good point
I was thinking the very same thing.
Yup I was thinking about this myself
I believe he mentioned that the headgasket was leaking so it would probably blow up after 1st/2nd run
Great video, great info!!! 👍🏽
Im having a hard time with my cold idle and im missing parts for the electric choje so im going to go manual best option i see
This really takes me back! Must be hard for young people to relate to fixing cars that had no "code readers". To me, being a good mechanic was as much an art as a science. BTW- I don't believe I have ever seen you look more self-satisfied and perhaps proud of your work as you seem to be in this video!
Great video. Good how to and why. Ghanks.
Do you have any recommendations for tuning triple mikuni phh at 6,000 foot elevation? I'm in Denver and have a '74 Datsun 260z
Good job with the Fairmont!
Question ? I have a 91 ford spectron . On a cold start it will fire up and idle but as soon as you hit the gas it bogs down strait away .I have to gently feather the accelerator to get it warmed up and revving normally . Takes a few minutes for it to warm up so I can drive off without it cutting out . Once it's warm it start and drives normally although it still bogs slightly on acceleration in the lover revs .
got some ideas fixing my 1989 mitsubishi lancer. thanks mate for the guide and explanation.
Thanks for this video I didn't know that the thing on the back of the carburetor, choke thing adjusted by loosening the screws. That may be the problem with my inline 6 300. It's a start anyway.
you answered my question with the ist thing you explained. Thank You
Thanks, need more videos like this, I was born in the 90s had no car guys in the family that were still alive and I always wanted an older car because the new ones both look ugly and because I wanted to save some of our heritage and keep it on the road, that being said I didn't know jack shit about carburetors and this helped me understand the various components of these complex mechanical devices, carbs were always something I was really into just because I mean.. think about all the parts in it just to give these massive machines life, that is probably the coolest thing about them and you know one day this could be a lost art, terrible!
hie bro hope u good.......you know what almost same situation 90's guy and always loved the old school ride though the knowledge part...hop yalz keep enjoying the journey ...peasce and love bro from Zimbabwe
Great video! Looks like the exact same motor as in my 79 Granada. I noticed the EGR valve rattling towards the end when the engine is idling. Mine does the exact same thing. Its not connected to any vacuum source yet. Any thoughts on this inherent rattling of the EGR valve at idle? I know you hear it. Thanks.
NIce job I learned a few things!
I need to rebuild the carburetor from a 1982 Toyota Tercel with 3A-C engine.
Being a California emissions spec, it has a heavy load of vacuum lines. No joke.
Luckily from factory, the mixture adjustment screw is sealed and no one has been able to fiddle with it since factory, so that part is ok.
The problem Im having is that at idle the emissions are high (around 800, it should be no greater than 120 HC) it will not pass emissions test.
Thank you sir great video
I want to send my Carburetor to rebuild to you :)
Thanks for the video :) 2 Thumbs up
I know I have one I would love Eric to rebuild for me as well seems there is not many out there that do it any longer.
nice work !
Thanks for the video. I have a question. I took apart my summit 4brrl carb and mixed up the nozzle bars. How do I identify which is primary and secondary. One has 2 jet looking pieces and the other just has 2 hole in the same spot. there is also 1 ball bearing and a rod that would sit on top of that then a hollow bolt that fit over that. Im guessing these fit with the nozzle bar with the jets?
you are going to get a ticket with that new carburetor ! :)
Nice to see old technology brought back to life.
What is that part that make that noise and why goes to the air cleaner?
Im impressed by your patience & problem solving!
Hey Eric, How about doing a video replacing timing chain and gears on that model. The parts are inexpensive. I would like to see the change in performance also. Thanks
could you make a video on idle cut-off solenoids on carburetors?
Can you check for the functioning of the secondary throttle by revving the engine (looking the movemet of the secondary throttle plate)
I love your videos. I have a motorcraft 4350 and can't seem to adjust the choke to where it is as loose to the touch as yours is in this video. Does the choke only affect the car during cold starting or does it also affect it in some way while driving? I hope I didn't screw mine up lol.
hi, my car failed emissions yesterday. its emmiting too much CO at idle but the rpm are fine. Could it be more than just the A/F ratio adjustment
Eric, how do you feel about tuning a carburetor with an air fuel ratio gauge versus with a vacuum gauge like you did here?
How can i know which carburetor is best for my engine?Can i apply any carb or is there a relation between displacemente and the carb itself? is there any calculations to figure it out?
Where is your oil cap?
thanks from Egypt
I've been having an issue with my motorcycle. After I rejetted my bike (I put a higher flowing exhaust on it) it developed a hesitation at high rpms (right around 8k) and it stuggles to go past that point. The bike idles fine and just cruising around it runs fine. Before I rejetted, the exhaust popped a lot on decel and when I closed the throttle because it was really lean and it still pops on decel after rejetting but not as much, but more than it should. Could this be caused by a dirty carb? I checked all of the fuel lines and vacuum lines and breather hoses and everything's good. I'm thinking maybe the passage for the main jet and/or the main jet itself is clogged? This is my first time ever messing with carburetors. My bike (2007 Suzuki gs500f) has a pilot jet, a mid jet, and a main jet. The bike did sit for a few months for winter with fuel stabilizer in the fuel system and I didn't really do a good job with cleaning it when I rejetted because I figured the fuel stabilizer did it's job. I'd greatly appreciate some feedback!
people can complain about the fairmount project all they want. they've been SO useful to me
Good stuff!
Just found your post. A) I had this car but had a 4 cyl - I would have loved 20 second 1/4 miles. BUT you could put 5 bodies in the trunk. Great car to go cross country. I am working on an Autolite 1100. How long can a car sit with gas and still start? Did not start mine for 3 months due to maintenance.
Thanks Bro! Great video!
You’re the guy!
Good video, thanks. Please do a video on everything we should know but don't know about when it comes to using the vacuum gauge ;-)
Aren't Carburetors COOL!? 😊💯
Instant gratification when set up right. Cheaper to run in the long haul than most EFI systems.
One little note, you mentioned the Electric Choke Coil, and were 100% correct about it. You just didn't mention that it's only a quick warm-up system, for better economy/emissions.
The Dashpot Tube, coming up from the Exhaust Manifold, actually supplies the heat to keep the Choke open when fully warmed up.
I know that's probably irrelevant in this case, but since you do such a great job of educating the young guys, I felt like that detail was worth mentioning. 😉

Hi Eric i have a 94 Nissan Cefiro with a RB24S Straight-6 and it has a Carburetor
what do you think should be the idle? currently its on 580 or something when i start it in the morning and if the engine warms it goes to 600 by the way its a M/T
so my truck is carbureted and when I start it I will idle just fine but when you put it in reverse or drive it will die. to get it to move you have to put in nuteral and Rev it up in nuteral then drop it in gear to get it to move. Any idea
14:13 Cool. I know that Marathon and that intersection. I've nearly hit a deer on that road.
Thanks for the education of carb.. hehe. Something to learn.
I have an 84 Datsun that has really bad carb problems and it has a Webber carb. Got any suggestions for what I should do? It Boggs out when I give it gas and sometimes it dies at an idle
Intake vaccume means a strong intake stroke. A strong intake stroke can be influenced by a strong combustion stroke on another cylinder. So having good vacumme is a goid place to tune on. I use a wide band though.
when you hook up the vacuum gauge for the idle screw where do you hook it up to is it the intake manifold or something on the carb?
It looked like a port on the carb.
this helped alot I just bought a Suzuki samurai and can't find any vacuum leaks but she idles to low
Michael Sliwa my samurai idles too high! Around 4k. I’m trying to figure out what to adjust
wow such a difference from then to possibly now lol. what was the factory engine hp? 89ish? vs over 500hp with that v8?
