Recommendations on things to check for an upper flipper that seems to "crap out" from time to time (hit button like normal but sometimes, particularly after a few loops, feels like a limp wrist, partial flip)?
I changed the coil stops out from stock a while back which felt like it helped with the flippers overall (and I learned after the fact the gold dust in my cabinet was a sign that at least one had of the originals was failing). When I purchased the stops, I didn't know to also purchase coil sleeves, and so I'm going to order some now
It feels silly to pay to ship just a handful of sleeves, so I figure I can also pick up other items that would be good to have on hand (even if not related to the flipper issue). Any recommendations from this list? https://www.marcospecialties.com/pinball-parts/GX3273?VIEW_SIZE=60&VIEW_INDEX=0&view=list&sortOrder=SortProductField:totalTimesViewed
The only changes from stock I've made to the machine thus far are non-magnetic balls, coil stops, titan rubbers, and cliffy shooter/drain/inlane protectors. My cleaning/maintenance is microfibers, novus 1, playfield wax, and sprayway for glass.
Thanks!
