My Bally Star Trek runs pretty nicely now except for one thing: no matter how I adjust them, the rollover stars work for a while and then stop scoring. I'm guessing they've been adjusted too many times.
I've taken a look at some of the main shops, but I'm not sure what to order. Is it this? https://www.marcospecialties.com/pinball-parts/ASW-A1-162
Very grateful for any hints.
