When I'm adjusting the motor height, there is less than a 1/4 turn between a horrible screaching noise (stripping the pinion gear I would assume), and lockup.
Also...and this is very annoying...I can't lower the motor height. It just gets stuck, and I end up having to pull the grip plate off to pop the motor back out. I thought it was the grip that was causing this, but it's been replaced and I still have the same problem.
