Skip-- your Question;
<  I'm confused.  I thought from what I read on the LML that the problem you
had was a broken crankshaft.  Are you now saying that it was just an
overspeed?>

should be answered by the two posts that are not in order. But in summary it
developed like this.

After landing we turned prop through, No impulse coupling "snap". Pulled
pressurization fittings out of top of mag. No rotation of gears when turning
prop.
Pulling lower spark plugs. a long screwdriver put in hole couldn't reach
piston--both were at BDC. Rocking prop back and forth (not enough) didn't
seem to move piston.
Teardown confirmed;
1. crank /rods/ cam not broken.
2. Mag couplings broken-drive gears chipped
3. Prop pitch change/ hub ok
4. Prop Gov now highly suspect and will know early next week.
