Help! Leaking Holley Carb

I sounds like you have the wrong metering plate gasket.

I think Phillip has the correct answer here, If it isn't the power valve itself. If you replace the power valve with a plug remember to re jet accordingly. Damn Holley's! Jim

I've seen a few that have had the bowl screws tightend too tight repeatedly and cause the main body to pull in at the screw thread area. It keeps the gasket from sealing in the middle. Run a "new" very fine toothed flat file over the carb body and then a very fine sanding block to make sure the gasket surface is flat. Don't try to "Mill" it with the file, just take out any small imperfections. I have had to put a few in my mill and make a cleanup cut to get them flat.

I'm with Phil and Jim.....There are several different metering block gaskets.

Carefully inspect Gasket to block for conforming to all Holes and Shapes.
