Starter Problem

To me it sounded fine in the video. But the gear was already engaged from you pushing it out manually with a screwdriver. I would think it should retract on it's own even when you engage it manually. Maybe it's a little tight against the flywheel?? When you loosen the starter bolts can you move the starter any? Normally you can't move it much but sometimes even .030" can make a difference. If you can't get it to move any try doiing another video without having the gear engaged manually.

BTW: the teeth on the ring gear don't look the greatest but I have seen them startt ok before with teeth that looked that bad.
