Kevin,

Another thing that would be interesting to try is to make the flats
not quite flat, but rounded all across the flat.  Someone mentioned
they did their motor that way.  I wonder too if it's the rounding that
caused the motor to self-start, or maybe the rounding had the
effect of making the flat wider, and started the motor for that reason?

Just some things to ponder on     :)
