LPR problems

[Skwid]

I have a Palmer Rock on my Twister. I am pretty sure that it has gone bad. I hooked a gauge up to it, and aired it up. The gauge reads up to 150 psi. When I aired it up, it pegged the needle (past 150). I took the LPR off, replaced it with the LPR I had on my Addicted (Edwin's externa LPR), and the gun worked fine. I re-installed the Rock onto the Twister, and the problem returned (air leaking out of the solenoid). I applied air, then turned the adjustment screw all the way in, and all the way out. The pressure did not change. Any ideas? If it is the LPR, how do I fix it?

I would send the LPR into Palmers. Assuming you haven't abused it at all they should warranty the work. The only other thing I could think would be the problem is an O-ring is letting HP air though and that is buggering up the whole works. That means you should try to replace any external O-rings before sending it in just to confirm that.
