Don't feel stupid... it's a learning thing. I've been wrenching on rigs for a long time. But there are cats on here that have forgot more than I will ever know. It's always good to get some info that is useful... no matter what your skill level.

And yes make sure you check the butterfly floats to make sure they are working properly, for all possibilities it could be bent slightly and you not realize it making it not be at it potential. I've had that happen as well.

??? Was it a Holley Spreadbore Quadrajet replacement carb? I don't believe Holley ever made a "Quadrajet".
