  7. Starter spins it, but will only start with the pull rope.

    Yamaha Wolverine 350 / 450
    The starter button works fine and the engine spins over, but it will not fire. One pull on the starter rope though and it runs like a top. Wierd. I changed the coil, not expecting much. No change. Maybe the starter is drawing so much current that the coil is not working properly...
