That virtually guarantees that the problem is one of two things:
1) stuck/bad (open) centrifugal switch for the start windings on the
motor
2) bad start cap.


I'd be tempted to try some 'impact engineering' to see if one can induce
the centrifugal switch to close. Proceed at your own risk. grin

I'd be glad to check the centrifugal switch - if I knew what it was and
where it's located. It's not on my exploded view diagram.
