*assuming you have already tried all the normal stuff in this thread >> too tight to pf, flipper button switch needs adjusting, etc.

It is quite simple to take apart a flipper and put it back together. That is always my #1 on any game with an issue. I also replace the sleeve at that time, bcause they are cheap and easy to do when apart. Also I got burnt on a few Sterns with bad sleeves causing binding so i learned my lesson.

I think this is the most likely cause of most people's issue; since it seems to be found only during longer play sessions.

I have had zero flipper weakness issues on mine, but I also adjusted flipper builds to my liking right out of the gate.
