53 Cavalier, I'm very familiar with that screw. It's very difficult to loosen since I'm bending over the fender, reaching down and it's not visible without placing a mirror underneath. I've replaced the screw with a threaded rod inside a spacer tube to bring it out where it's visible. I have set the plate at 0 thinking that would be a good place to start.

I was getting a vacuum reading just barely into the normal zone, dipping sometimes into the low zone. I suspected the vacuum advance might be perforated, so I ordered a replacement from Max Merritt. The Merritt advance matched the existing one perfectly. Thanks again for all your help.
