Quoted from HC2016:Got a tech question about the right flipper . Playing the game for about 2 hours and I’m noticing the right flipper isn’t coming back to its resting position. It’s starts out with a pause , and as I play more it actually sticks in the active position. This is only when the game is in constant use after a few hours . I know that right flipper gets a lot of hold during the play to make the good shots . Could a coil be getting overheated ? Thanks in advance for any input .
Very likely a broken coil stop. Stern is notorious for this. Pinball life has very good replacements that are more durable:
