- In part 3 of rebuilding a Holley four barrel carburetor, we install it on our car, get it running, then make the initial adjustments to make it run correctly. These adjustments include idle mixture, float adjustments, idle speed, and making sure the accelerator pump circuit is working correctly.
While we made this video using a Holley carb we rebuilt, this video show exactly what is needed to be done when you buy a new carb as well.

Thank you. Your series on rebuilding and setting the carburetor have been invaluable to me. Thanks to your videos I was able to fix my carb!
Great to hear!
This is the best Holley how to video I've seen
Glad it was helpful.
Great video, now I'm confidant about rebuilding my carb. Thank you!!!!
Thanks for watching. Glad it was helpful.
The whole series is super helpful and very well explained. Thank you for taking the time to do that.
Glad it was helpful!
Your videos are very informative and the step by step instructions would definitely make anyone’s first Holley rebuild a breeze , keep ‘em coming !
Wow. Getting set to do a rebuild on my '85 Mustang (factory Holley). Stumbled on your tear-down video (great) and jumped to the install video. Looks like you JUST posted it. Talk about timing. Very informative. My carb is a bit different (emissions) in that it has the idle mixture screws in the baseplate and they're sealed in with plugs (tamper proof). Should be interesting. She's nasty. Your videos are excellent.
Thanks for watching.
Спасибо! Перебрал свой карбюратор с помощью вашего видео:) Осталось правильно это все настроить и отрегулировать, что бы заставить работать на своем 302..) Не могу понять какие форсунки и силовой клапан лучше поставить, у 302 небольшой объем, и заливает свечи
😊great video bro I have same carbe put in my Holden 😂
Very cool. Thanks for watching.
Do they make a rebuild kit for ethanol gas . I'm having trouble with my gaskets leaking. Thank you. Good information in your videos.
I run all my cars on 10% ethanol with no problems with any of my carbs. The new kits have different rubber parts that handle the ethanol better. They just don't recommend letting the gas sit unmoved by running the engine for months at a time.
is that the 390 engine? if so i have the same engine and Carb, i have to spray gas directly into the carb for my car to start, i've taken it down and cleaned every part of the carb but no change, any suggestions please? it's a brand new carb but i had it sitting up unused for years, it's a restoration project
428. Is this at every start up? Or, just after it sits a few days, weeks?
Great videos. I have the exact same carburetor. however it spits gas out of the forward vent tube like a geyser. Any ideas as to why?
Make sure the needle and seat doesn't have something stuck in it holding it open. If you're using an aftermarket fuel pump, be sure it isn't rated more than 7 psi fuel pressure. If so, you will need a pressure regulator.
I rebuild my holly but its running way to rich the idle mix screws doesnt do nothing even if its all the way in still 2 rich
Check float levels, and if you're not using a stock fuel pump, check fuel pressure.
How many turns are on the secondary stop screw at initial setup?
The stop screw is missing from. Carb I neet to rebuild.
there really isn't a specific turn number, it's more about finding preference of high idle speed for your particular set up. I like my cars about 300 rpm above normal operating rpm. It's enough to keep the engine running when cold, but isn't hard on drive line when trying to drive the car.
Friend, I have a 4160 carburetor, I put it in a '75 302, washed it and rebuilt it with new gaskets. The engine does not start until you accelerate but it does not idle, I release the accelerator and it turns offIn the same way, when it is kept accelerated, it expels explosions. What would be the problem? Is there any hole covered?
it does sound like a vacuum leak.
I think the same but I can't find where
I can't get my choke coil on my holley 600 9834-3
Are u just running a 3/8 line to carb?
yes. This car came with that stock. The hard from fuel pump to carb is original.
What causes a4160 to stumble on a 302
There is an old saying "80% of carb stumbles are lack of ignition timing."
just wondered you say you are not vacuum advanced how is that i see a distributor with vacuum
I was not using the distributor's vacuum advance at this time, so I didn't hook it up.
