This is why I prefer kick starts. The teeth are gone, and has worn the teeth on the new starter motor. The gear shaft is broken on the reducer gear. And now the damn flywheel won't come out. 🤦🏽♂️What happened to the teeth???
But if the case is not damaged behind the gears where the support shafts hold them it isn't so bad. The gears can be replaced easily, not the engine case.
