The starter gear teeth on my lawn mower has been sheared off. As a result it is not engaging the flywheel. When I turned the key the first time, the flywheel engaged but the mower did not start (the choke was not engaged), so I tried it again, and that's when it started to make a high pitched noise. Could there be extra stress from the flywheel that caused it?
Any ideas what might have caused this to happen?
