Just by happenstance this weekend we had a starter quit starting on a Ford 300-ci stationary engine. All it would do was 'clack' but wouldn't turn. This was OEM 1968 not previously touched.
Took it apart and found the shaft was bone dry. The spur gear wouldn't throw forward when the magnet tried to engage. You said yours wouldn't turn when engaged. Try lubing all the rotating parts without slinging grease everywhere--a dry sleeve bearing or something similar could be a problem.
I used two drops of Kroil on the shaft and a few daubs of white lithium rebuild grease, worked everything by hand, benched it, and it whirred like new. Back in business.
Please post back your continuing experiences so we may all learn.
