Tuning with jets, Power valves and an O2 guage

I meant to map the curve today but got tied up in other matters.
Yeah, my advance starts just off the 1000 rpm idle. By 2200-2400 it appears to be all in. That seems way too soon to me. I have 2 MP electronic distributors. The one I have had for 11 years is the one that has the lightest springs and has been adjusted to a 13-14 degree advance. I took the advice of a FBBO member and emailed Don at FBO about getting the distributor recurved and phased. Instead of a simple "Sure, send it to me" response, Don asked a series of questions. I take this as a sign of good service. I had planned to send him my spare MP distributor. I'm going to call him on Monday.
