1973 65HP 3 cylinder, new to me. I found starter gears grinding due to stripped bolt on starter-no big deal I can handle that. Question is: should the gear fully engage the flywheel? it only engages about 50% and the wear pattern on the fly wheel only covers half the teeth. The starter that is on there can't possibly fully engage, Im worried that if I replace the gear and fix the stripped bolt that it still won't fully engage and will fail prematurely. If it needs to fully engage then I think I may have the wrong starter and need to replace the entire starter. Any input?
