    have 81 350 with a quadrajet carb. pump is pumping fuel to carb, but no fuel going through carb. I got a rebuild kit and re-did the seat and needle, the bowl and everything was all full of corrosion. cleaned everything and put it back together, and nothing.. still the same thing, like the needle isn't letting fuel in...? what do I do? I need it fixed cause it's part of my plow fleet.

    So when you pump the accelerator you don't have fuel spraying in the bore?

    But did you remove the fuel inlet fitting and clean it out in there including removing the internal fuel filter? If not that's likely your issue.

    I know a guy that likes to loosen the fuel inlet and turn the engine over to see if he's getting fuel to the carb.

    I know another guy that recommends having a fire extinguisher handy during this test.

    yeah, I have started it on fire a few times... I am almost ready to just buy a new carb, I just don't want to spend the $400

    Doesn't tell me much...Did you verify the fuel inlet was clear through to the seat port in the fuel bowel with compressed air? Did you do the same thing after it was re-assembled? Just the basics you do during and after any rebuild to verify unobstructed flow.
