Up/Down ramp now working well. I did not have to dremel the washers. All I did was take it apart and screw it back together and possibly screwed a bit tighter then the factory. Back together and working well and zero hang ups in 40 plays or so.
Orb/Mummy captive balls holding well and I recommend adding loktite to metal shaft to avoid further issues. They are both registering well.
My last remaining issue is the sarcophagus tunnel switch above left ramp. Many adjustments and it's still only working 70% of the time and sometimes the ball just hangs up in tunnel near switch and I need to shove the game to get to move onto gate and other times it goes all the way to gate and does not register. Usually it does not register when you really need it to and it's a bit annoying. Anything easier than changing to a Williams switch as I have yet to get this right?
Game is my favorite pin of all time when working, so that says something. Just one fix left, I guess.
