Quoted from Frax:Stern uses some really CRAP coil stops, and that's been the case for years.
This is what I find on the vast majority of sticking flippers on stern machines...I rarely ever use a rebuild kit as these fail LONG before the plunger ever shows any sign of wear; although I do replace the coil sleeve every time because its a cheap trow away part and there is no extra work involved with replacing it.
The dead giveaway here is is you see a little collection of brass dust at the bottom of the cabinet the coil stop is going to be bad.
Quoted from Phatchit:5 bucks it’s the coil stop . It gets mushroomed and causes slight burs and it catches causing it to stick. Order at least four and keep them as back up .
No bet ... but not from mushrooming, the brass retaining rivet will never last long enough for that to happen.
