Mike, before you get too concerned about magneto parts, consider that often the ignition coils on these old motors are good. First thing that I would do is clean the points on each motor and pull them over to see if they have spark… you might be pleasantly surprised. If no spark, do you have a way to test the coil? There is a simple test that can be done with just a VOM meter… not absolutely definitive but a first indication of condition. Also, old condensers are always highly suspect… and easy to change with generic condensers of .22 mf size. condensers.
But first clean the points and try… Let us know what you find
