Got an Invasion in a trade today. Aired her up, a small leak was coming from the back of the gun. I can hear it through the bolt chamber, but it is very minimal. I shot the gun, which I could tell was over pressurized from the amount of kick and noise, so I figured that could be the cause of the leak.
I have been a strict timmie owner, so I screwed both the inline and LPR regulators to flush. That stopped the leak. I pressurized the regs by one turn in from flush on the inline and 1/2 turn in on the LPR, no shots. After some trial and error, I discovered the gun shoots fairly close to normal velocity, though I do not have a chrono on-hand, when the inline is be about 1 1/2 turns in from flush, and the LPR about three from flush. The leak still occurs though, starting when I turn the LPR even just slightly in from flush.
I assume the cause of the leak is either in the ram or the LPR, so I will clean both when I have the time.
In the meantime, anybody have any ideas as to what exaclty may be the cause of the leak? And, considering I have no pressure testers nor chrono, what ammount of turns in from flush do most invasions run at? Just so I have a basic idea of where I need to be.
