Re: Leaking Holley carb.
Jeff - What is the list number of the carb, and does it have centre pivit floats or side pivit floats. Does it have the Brass floats or the nitrophyl (black) or the duracon (white plastic). Also is the fuel coming out the front boosters or the rear secondaries?. How much fuel pressure do you have? How big is the engine, and how much camshaft? Need more info to try to figure this out.
Take the carb off and turn it over, are the throttle blades about 1/4 to half way up the idle transfer slots? If they are a bunch higher it is probably pulling the fuel out of the boosters, which is normal with too open a throttle blade.
Post all this info Please.
