mine does have worn teeth on ring gear, but also if you look at the fork in starter that engages the starter drive, mine has worn the forward part of the lugs that starter drive ring runs around. Not sure what to do yet, can't find another fork, turning them to a new forward face does not appear easy as does welding and grinding to fill flat spots. thought about allen head bolts to replace the worn parts but not sure how feasable that would be. any other input?
