The player stepper unit in the backbox. Seem to have a situation and I need to know what it looks like. Seems the game starts and only plays on player 2. But manually moving the stepper, it only goes 4 notches and then hits a 1/4" flat spot in the stepper sprocket. Looks factory. The zero out stud hits in the frame in the correct area. The pin that triggers the switches when it's in 0, are hitting, but this flat spot seems to be in the wrong area or not suppose to be there at all. Anyone have a picture on what the gear looks like for the player stepper?
