With a new starter installed the you can hear the motor spin put the drive gear will not go forward. Take the starter out hook it up to a Batt with jumper cables and the starter works great. Put it back in and the starter spins but the gear won't go forward to engage the flywheel. I ran a ground wire from the Batt to the starter to be sure it was grounding and it did not help. Starter works great out of the Gator but not bolted in. No grinding noise from it when installed, grea just won't go forward.
