Many years ago I saw a very old offset press with a large flywheel powered by a universal motor. The shaft of the motor had a small rubber like wheel that rubbed against the flywheel. There was a foot peddle that changed the position of the brushes on the motor, which in turn would increase the speed of the motor.
So, I've seen the speed of a universal motor controlled by changing the position of the brushes.
So is it possible by altering the position of the brushes on a 6v starter we could slow it down a little? That way when we use a 6v starter on 12v conversion, the starter drive so won't engage so hard, which can possibly damage the starter drive and or starterring? At the same time the starter will produce enough power on 12v to start the engine?
