Bob,
Your photos show an unusual condition. Your gear engagement was WAY looser than what anyone else has indicated. The pinion has been climbing over the ring gear. Not much wonder it has worn so badly. Obviously there is far more crankshaft location variation than what should happen during assembly. I would expect maybe .010" difference, but your bike must have been off .060" or more.

Factory tolerances need improvement.

While the flyweight spring is the critical setup issue, it can't overcome really poor spacing. For the purpose of a starter, the gear tooth engagement is not terribly fussy. All it needs is from slight play to moderately large play. Yours was grossly excessive.

Excellent work finding alternate sources for lower cost parts.
