Just noticed that some motors have a rotor in which the slot for woodruff key is dead center between the horizontal lobes rather than at a 1 o'clock position. Not sure what crank these go on (assuming slot in crank has moved too). Looking thru old ones, I have about 6 or 8 of each type.

Next time you have a mysterious lack of power after working on one, check this.

I'm guessing the centered ones can go on either way.
