The gear is under the shroud. It's going to be single digits here for the weekend so if a heat gun doesn't pep it up tomorrow morning then it's going to wait a few days. I have a spare starter I pulled of a scrapped engine but I really suspect the only issue is the cold.
It’s just around freezing here and I decided to move my riding mower from the garage to the barn for winter storage. The battery is fine but when I turn the starter it just spins and doesn’t engage the flywheel. I assume the cold is causing the bendix gear to not rise, maybe from cold grease...
