I'm not sure I know what you mean by an adjustable dwell.  As long
as the motor runs at the correct speed, AND you can adjust the
rotor position relative to the incoming ac sine wave (the phase adj),
you'll be OK.  Then just adjust the phase for best spark output.

I've always wanted to try this electronic speed and phase control
method you're using BTW, but never got around to it.  You've
basically created a sync-gap by electronic control means.
