Re: starter drive
dmsfrr, you originally said the same thing I said, but I just said it differently, hopefully adding a few clarifications.
Now lets look at the cut-away view of the starter drive in fig 23 on page 244 of the '56 Ford car shop manual. You can clearly see the lock pin and detent which hold the gear OUT (or engaged with the ring gear). The lock pins do not engage until the ring gear is rotating around 300 RPM's, then they disengage, allowing the starter drive gear to worm its way toward the back (disengaging it from the flywheel).
Once the flywheel gets going over 300 RPM, the locks pull away from the detent and the ring gear rotates the starter drive gear back (away from the flywheel).
dmsfrr photo shows starter drive in it's normal position with engine not running.
