What were you able to figure out while troubleshooting your flipper? Was it the EOS or something else. I'm having issues with my right flipper and I checked the EOS and flipper bushing (both seem fine) yet the right flipper is sluggish to return to starting position. I shouldn't have to replace coil sleeves on a game that's less than 200 plays, but I guess that's next to check. Was just curious after reading your post on what the outcome of your situation was?
