...............the rotor is supposed to turn back and forth,the springs pull it back to the base setting, thats how u get centrifugal advance..........kim.....
Good point. You should be able to "spring" the rotor against the mechanical advance spring, and it should "snap" back when you release it. This of course is just a fraction of a turn.
The OP said "freely." I assumed he meant he could turn it more than one full turn
