    Help Needed - Spring found stuck to 750 motor flywheel - where did it come from??

    Hello. I pulled this 750 out to change a stuck starter bendix and install a crankcase blockoff plate. When I pulled the cover off the front I found this mangled and torn apart very small spring stuck to the magnets on the flywheel. Any idea where this could have come from? I am thinking maybe the front crank seal but have not removed the flywheel yet to inspect (need to get a m18 bolt). I also see oil residue in the cover and on the stator (see pics). Could this come from the front engine seal or a bad oil pump (pump while installed was not being used)?

    Looks like the spring that holds the weights in the rear of the bendix.

    Interesting as the bendix did completely die (it was going in and out all summer).

    Does look like a bendix spring. Turn your bendix to open it up, and look inside. Could be crank seal spring.

    Either way, you are lucky you found it now.

    Update: I pulled the flywheel off and the spring is still on the front engine seal. The bendix is stuck so I will need to pry it apart or something so I am guessing the spring is from the bendix. Weird thing is I had a strange miss at low speeds that is on my list to diagnose, maybe that spring was working its way into the flywheel or maybe at low speeds it played havic in the electrical system. Waiting on new crank seals to come in before reassembly.
