Something must be goofed up, 20 is at 750 RPM with the vacuum advance disconnected .I was asking questions earlier about full advance and initial timing because I was having this problem. I better take a closer look at some things. I will double check, but it seemed like I was all in at about 2200

Sounds like your curve is starting too soon, put heavy springs in it and check it, if the base timing comes down that's the culprit (your idle speed will drop too). You'll have to start moving springs around to get it dialed in. Try a heavy spring with a light spring. It's OK to mix and match the springs to get what you need.
