Okay. I've been given an E-Bladed Prostock to fix, the problem being a leak from the front of the solenoid. If I wind in the LPR, the leak gets progressively worse. As I wind out the LPR, the leak reduces, but the gun doesn't have enough pressure to re-cock itself. I've stripped, cleaned & lubed all the seals in the solenoid. Stripped & cleaned the LPR, but it's made no difference. Input pressure to the gun is 800psi, which I'm told is correct. It's running the standard Pro-stock vertical reg, which I'm assuming is still at the factory setting. Can anyone shed any light on this? It's driving me insane!!!
