Holley Carburetor

I posted this on an old thread, so I decided to start a new one. I am in the process of rebuilding my Holly 80508 750 CFM with kit 37-754, and I have a question for you Holly guys.
I am getting fuel between the main body and the metering block with the car not running. I think this is supposed to be dry. Primary fuel bowl is leaking down sitting there, the float is set correct and a little to the low side. could the new power valve that came in the kit be leaking?? Thanks a bunch....
