4 corner idle? What's the duration at .050?

Make sure the slot is slightly exposed on the secondary as well. The secondaries can not be completely shut.

Open the secondaries so you can close up the primary side.

Vacuum will likely increase as you clean up the rich idle. I wouldn't worry about the PV selection right now. You might even put a plug in it just to get a clean idle, removes another potential variable. Get the blades reset and then tune it up.
