Edelbrock Carburetors?

I am in the process of rebuilding the Holly 80508 750 CFM with kit 37-754 and I have this question for you Holly guys. I am getting fuel between the main body and the metering block with the car not running. Primary fuel bowl is leaking down sitting there, the float is set correct and a little to low side. Could the new power valve that came in the kit be leaking?? Thanks a bunch...
