Hi Lucky do you know how long ago you changed it, as mine still bounces up & down, but in the gat it keeps dropping & spiking off between 190 - 260 & it's been to Planet for a service & we've stripped it down, changed the hoses several times & the only thing it can be is the detent spring is worn down...I believe this is what your after?

Bit of a bad picture but chrome hex nut cocker detent like in the link. Don't know if there's any difference but it came off an 04 cocker, it's got a bit of loctite on the threads still but it bounces up and down so it should be good.
I only changed it because i'm a gun tart and i found a sexier oneDoh?
Cheers Cliff...
