Default carb probs...

well today i was picking up my car from the mechanics and he said he test drove the car and everything was ok. WELL, i got about 2 miles down the road with my friend in front of me and the car starts to sputter then ultimately dies...yea i know, wtf. I went bak and got the mechanic and had him come look at the car as it would not stay alive for moe than 5 seconds. Found out that the carbs floats were bad and the carb was leaking gas down in the motor. So i had to go get a new carb. I just want my car back!

dude, you got hosed, did you at least get a reach around? Even concidering the float was bad, thats a $12 part. Think about it, do you really expect that you have to trash a $400 carb for an internal part?
In here we need basic info on what ya have, that way we can help, thats wy we are here.
Did you keep the old carb? If not, what did you get for a core charge?

What I mean is Engine? L-48 L-82
Stock? any engine mods ... Intake manifold/Ignition timing ect:

Hard to diagnose a problem without knowing the specifics of the engine

Unless it was an old 2 barrel carb I doubt it was too lean

I bet you that carburetor is totally rebuildable. Probably just needs a good freshening up. One thing about a Holley, they will ALWAYS end up leaking at some point. That's just the flaw in their design.

Unless I mis understand the problem if you are getting gas back into the carb, the floates may be out of adj. If the floats are to high it will cause the extra gas to flow into the main throttle body. Once this happens the car will not stay running because it is drowning in gas.

Just a thought to consider.

You're getting ripped off. Have the car trailered to a reputable mechanic, get your carb back, and tell them there is no way in heck that you're paying for a new one.

i myself think the carb was too lean because it was just a 650. Most strokers usually need a 750 or higher. Yes the carb was working when the mechanic test drove it and a day later when i was driving it home. Its just more like a freak accident kinda thing. Idk y u guys r hating on the mechanic when he did nothing wrong. I would also say that the carb is old but then some of u guys would come up and say "hey i got this so-n-so carb for so long and its still working yadayadayada. It was a hand-me-down btw. But the carb was just scarin the $hit outta me becaue even when the motor was shut off fuel was still flowing into the butterflies. Heres the carb:http://www.jegs.com/webapp/wcs/store...tegoryId=10271

Its just a replacement
for Quadra-Jets.

The size of the carburetor has nothing to do with it running lean or not. CFM is simply the amount of air the carburetor will pass through the bores. Jets, metering rods and air bleeds are what set the fuel air ratio not carburetor size.
