How To Rebuild A Holley Carb, Part 3: Installing The Carburetor And Making Initial Adjustments!

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!

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.

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

Do they make a rebuild kit for ethanol gas . I'm having trouble with my gaskets leaking. Thank you. Good information in your videos.

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?

[prayfawind]

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

Great Videos. I watched all three. So I have a 1987 Ford RV E350 with a Holley partnered 4bbl. I don't have any room in there to do all these adjustments. I have to build it, slap it, and go. I was thinking the screws on both side, just turn out 1.5 times. Hopefully the floats will be correct, and go. I may be able to adjust the floats. I'm nervous, never rebuilt a carb, but it's leaving from the accelerator pump center, onto the manifold. Will just doing the basic idle screws be enough? I'm not looking for extreme snappy performance, just go, secondary works, and it doesn't leak.

Also...can you assist me with what kit to get? Holley built it for Ford, but the list number doesn't have an 'R' at front, so that Holley chart doesn't seem to work. The List number on the carb is 50260-3 Manufacture date is 2616, so it was manufactured June time frame 2016, but it's an RV, and she has sat a lot. I just got her from the Lady who owned her before. Carb is a mess. It's electric choke, and I'm guess vacuum secondaries. Interesting thing, is when I first got it running, the down kick didn't seem to work, but I've driven her a few times, up until accelerator pump started leaking, and the kickdown did work one time, otherwise it was just dumping gas until it went faster.

I'm so nervous about rebuilding her. I'll be using the carb cleaner in a can, and compressed air in a can...I don't have a big shop or garage. Your videos have calmed me, but a couple things, my fuel inline is different than yours, but the core carb, I presume is just like yours. Could I use that same Edelbrock kit? Internet isn't helping with that 50260-3 number.

Thanks for the videos and your time.

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

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?

I can't get my choke coil on my holley 600 9834-3

[claudeslaton]
