good tip by the other guys . as it is the real flywheel , same for almost any small engine and good it didnt try to start mate . as ihatewetsocks said , it WILL HURT even now when a broken flywheel key it still hurts diognosing

the flywheel on theses is really only for cooling as not much weight to them so they NEED a steel plates maybe not blades though
