AeroVee pg35. When swinging the propeller by hand, it was found that the flywheel trigger contacted the starter housing's unmachined face which was incorrectly fit up with the solenoid outboard due to the stator plate incorrectly clocked to one position CCW. The stator plate interference with the starter solenoid was the cause of the incorrectly installed starter.
The starter was unbolted from the frame and the starter face with a machined clearance was on the outboard side. This led to discovery of the incorrectly clocked stator plate.
The stator plate was unbolted and clocked to the correct position.
The ACV-Z01-12 screws were left loose waiting for Loctite 242.
Starter awaiting reinstallation.
