power valve hitting the base plate screw "boss" in the vac. chamber not allowing the m/block gasket to seal to the venturi surface. this is a common problem with "older" venturi's. check a new venturi an you'll see what i mean..

this is also made worse if you are using the new non-compressible p/valve gasket with a mill'd surface of the venturi as they become closer together.
