Onan’s plastic starter motor gear breaks easily Alternative?

I have not tried to check that. I have ordered a new starter motor for it. Once I drop the genny, I will check the flywheel.

Not sure if that is the problem though.....because when the genset runs, it runs absolutely fine....runs fine on load as well.

How hard is the flywheel to turn by hand ? If its to hard to turn the valves may need set to spec.
