When housing Holley power valve plugs make sure that the head of the plug is not hitting. The main body there is a boss that sticks up on the main body, grind the casting flash off the plug can use a belt sander, lath or big file. When you take the carb apart inspect the body if it was hitting you should see it on the plug and main body. If it is hiting it keeps the metering block from fully seating on the main body.
