356 starter not disengaging

1947 Packard 356: this 4052 starter cranks the engine fine, but makes a terrible noise when the engine fires, like it's pushing against the flywheel, when the drive should be thrown clear. We took the starter completely apart: everything looks good. Relay points were cleaned and set to .030.

I've played with carb starter switch and set against another good 356. The flywheel teeth look OK. Any ideas?
