carb help, Holley dbl pump.

Just because it has power valve plugs it doesn't mean the gaskets are not leaking. I've fixed a lot of complaints lately because of gasket failure. To check to see if that's the problem fill the bowls to normal level, remove from motor and put on a carb. Fixture to elevate at least 2 inches. Wipe the bottom of the baseplate to make sure it's dry, let it set for a while, recheck to see if it's leaking, if it is it will becoming out the p/v vac. Port in the base plate. Then proceed to disassemble and repair. Caution: With the holley p/v gaskets it's easy to over tighten them and then they trar apart. Not so if they are after market with the teflon coating

hope this help's.....norm
