hey guys, heres my prob. i yanked the 350 out of my ride and im cleaning parts. heres the thing i have a 600 cfm 4 bbl holly. its still good but its filthy and i want to put a new rebuild on it but im worried i might ruin it,being that carbs are delicate aand i dont know that much about carbs, what is my best bet without having to buy another carb?
yeah i think its a good idea to, figuring i dont wanna fork out another 3 bills for a new one. what should i expect to pay?
oh man that a good deal! wish i had the money for that right now! damn it!!! well i guess i have no choice but too have it rebuilt, man what a burn, maybe ill get lucky and find another deal on ebay. thanks bro/
fuel system parts will rebuild your 4bbl for about $200 and tune it to your car on a dyno for an extra $50.... i dont know if they have one where you live... but they are nation wide
Rebuilding a Holley is about as easy as it gets. There are many books on the subject, some good choices at www.summit.com and they also sell the rebuilding kits. Getting the parts clean and free of debris is the main obstacle. All passages, no matter how large, must be thoroughly blown out.Quote:

I agree with NTFDay, Holleys are the easiest to rebuild, and theres not too many things that are delicate in them either, probably the most delicate parts are the accelerator pump diaphram and power valve. There aren't too many parts in there to confuse you. Rebuild kits aren' that much.

It sounded like he wanted something ready to go, and one that had been rebuilt and run in and set, for that price, sounded pretty good. But, by all means, I think he should buy a good book, and try to do one. Nothing like doing one to understand what's going on.
Learn the 6 circuits, and you will always remember what you want to do, because you know which circuit it happens in, if there is a problem.:)
Well said :)
yeah, i could go and get abook and try it out , and learn the parts but then if i screw up im screwed......
Ya, i agree that you should try to rebuild it yourself. Im new to all this stuff and i took mine apart and changed the jets and power valves and so furth and didnt think i was doing it right so i sent it out to be professionally built and it comes to find out, i knew what i was doing and wasted about 300 bux for it.
rebuilding a carb really isn't that hard.... i never tried it before, had one go out on my car and rebuilt it in no time.... minus the soak time.... takes about an hour to do a thorough job
Sure, go for it, thats how you learn! One caution--don't overtighten the four screws on each float bowl, you can warp the carb body and cause all kinds of problems. It can be filed flat again, but better not to do it in the first place. You should check the body with a straightedge when its apart anyway.
hmm yeah you guys are right, i should try it to learn and all, i think ill go buy a book and give it a shot, but say if i do ruin something how would i now when i try to run it besides the engine not kicking over? or running it without not knowing somethings wrong with it? ah what the hell, ill do it. thanks guys.
just do the rebuild and then when you put it back on, of course dont fire it up. Let the fuel pump run and get gas in and then make sure of no leaks. Then after that is the hard part of trail and error and also, trying to determain what you think is the best. Thats the hard part.
Also don't overtighten the four small screws that secure the accelerator pump housing. They strip very easily and will cause more grief than overtightening the float bowl screws.Quote:
