"The Rotor advances, No argument about that. Everybody Get That out of the Way."
This depends on your point of view. I contend that from the pick up's point of view, it does not advance. From the pick up's point of view it stays exactly in the same place. The mechanical advance puts the engine in a retarded state when it comes in. The timing light will show the rotor staying in the same place, while the engine rolls away from tdc at the exact same time.
