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?

So I took the entire flipper assembly apart and inspected it. Nothing wrong, so put it back together and now it's working fine. Must have been binding on something that wasn't too obvious.
