Ok, its a shocktech e2d Cocker. I recieved it in a trade recently and when I first aired it up it was leaking. I took most of the gun apart and put back together and it is still leaking from the solenoid. the back part of the solenoid has a small circle with a phillips head indentation on the piece of plastic. I have not taken that part of the solenoid apart yet and that is where it is leaking. I do not know if it is supposed to come apart or not. I cock the gun, air it up with lpr all the way off and the solenoid will click, no leak. Once i turn the lpr up some it leaks from that part on the solenoid I talked about and it will not cycle ( back block move) it is a heavy leak and the more I turn the lpr up the heavier it gets. Any help is greatly appreciated.
