I have kind of an odd ball issue with my game. The left flipper button had been a little clunky at times, now it is popping out off the game. Does anyone have any experience with this? I tried to remove the button by taking the bolt off the inside; however, I was not able to get the thing loose. I assume I can order a replacement button no problem, my concern being able to get the original removed. Any feedback would be appreciated. (Amazingly there are no You-Tube videos out there on how to replace a flipper button on a Stern pinball machine.)
