Or maybe the gasket around the PV is bad, or missing, or loose - torque it down to a good 50 inch/lbs. The power valve normally is closed when you're idling, or trying to idle (because you have over 6.5" vacuum for that particular valve). This prevents any gas from "shortcutting" around the jet restrictions. Back in the 80's and before, a good back fire could break your PV and the classic test for checking for a blown PV was to turn your idle screws all the way in and see if your engine dies (meaning the PV was good). But Holley fixed that bug around 1990 or so. I know the odds of getting a bad PV in a new rebuild kit is pretty low, but that could be an answer....
