If the power valve is open, it can effect the idle.
Jon. Thanks for the post Jon, I've read some of your advice in reguards to carburation on other posts and was kind of hoping that I could flush out a response from you! I'm going to pull the carb off on Thursday and check out the seal on the power valve. It's a fresh rebuild but anything can happen right? Also, I have a collection of spare B series Rochesters that I can pull from just in case. Thanks as well for the link, I had found (and lost) that link earlier this year and I've been trying to find it again. Thanks for your help. What would you suggest that I do to eliminate the fuel seeping at the seam? It's minimal but it buggs me to no end! Is there a gasket sealant or even a better quality gasket that I should use? Should I set the floats so that there is less fuel in the bowl? I was told from a local shop that a high float will also cause the engine to idle fast. Is it possible that excess fuel in the bowl can runoff into the air horn somehow? Thanks again for your help. -Tim "Doc"
