Welcome to Aussie pinball I have a jungle princess so when I get a little more blood in the Johhny walker system I hope I can help you out.   Double check that all your stepper units and score reels are making it to the start position.   Check out the one on one section I've made up threads on Joe tonrebuild each unit.
