Starter spins the gear to the dampner, and goes through the gears to the one way clutch, that has to grasp to spin engine, and freewheel when engine starts. See the diagram above.
I would check the starter first, with starter off you can move the gears, and if they move in both directs, and do not lock in one direction , then you know it is the internal gears and have to open the case! I have not had one apart.
I see question is still open, please rate to close and get me credit! Thanks.
