Thanks Tubs.  My first observation is that I have not completely disassembled the and reassembled the ignition assembly, only taken off one part at a time.  Also, due to the length of the magneto wires and their routing within the ignition plate I don’t think they could be switched and last, the motor was running, then not, before this trouble began 30 years ago when I broke the recoil rope trying to get it going.  I just don’t know if back then it was running on only one cylinder when a second issue developed causing complete failure.

With that being said, I marked the center of the magnet on the magnet rotor as directed and reinstalled it in the keyway.  Rotating the shaft clockwise, when the mark gets to a set of points they are already open and as the mark passes the points they close.

Continuing to rotate the shaft, when the points begin to reopen the magnet mark is pointing to the general side of the magneto going to that set of points that just clothed so I think that is OK.

I’m giving it a break for the week.  I have a new set of condensers coming from eBay.  When they arrive, I’ll install them, reset magneto and points gaps, recheck continuity of all wires and try again.
