Help! Leaking Holley Carb

Next to the middle-front base plate screw?
That sounds like the passage that sometimes has an anti-backfire valve to protect power valves from blow-out. If it's not the power valve or its gasket leaking, only other things I can think of is the metering block gasket or casting issue. Double-check the metering block & main body gasket surfaces for any debris. Wouldn't hurt to check for casting warpage, but I've never seen that problem come up.
