Pretty simple get it running as good as you can with vacuum disconnected and plugged. get total where you want it and if it has enough idle advance to idle well in gear leave it and drive it a while. if it needs more idle advance work the curve till it does.

Then after driving and your happy plug vacuum advance into ported vacuum and drive if it pings put a 3/32 allan wrench in through port and turn counter clockwise maybe 3 turns to start and drive then keep adjusting this way 1 turn at a time till any ping at light cruise is gone!
