The first thing I would do is remove the left side stator cover to get to the crank bolt. 17mm socket on a ratchet should be able to turn the motor over by hand, counterclockwise. Make sure the motor isn't fully stuck. If it's sat for 10 years, the rings could be frozen to the bores. If it proves to be stuck. a little ATF down the sparkplug holes could free it up after a few days. Make sure the motor will spin and then look into the starter issues. Just my $.02
