Quoted from tedlogan42:Besides lubricating it, where should I start?
Dont lubricate anything on a pinball machine. It operates dry. What I would do is adjust the switch as it seems it may be out of aligned and not popping the ball up in shooter lane. Pick up the switch adjust tool at pinballlife.com to make your life easier, but if you must you can adjust it with your fingers. Good luck with it.
