Gen4 w/ Lurker Valve & Ram:
Oh right. Derp. I plugged mine and forgot the hole was even there. Brb.
Edit:
So there's definitely something up with the LPR pressure. It's sitting at about 25-30psi. The gun is fully cycling and if I bump up the LPR any further, it'll start leaking from the bolt port/body hole whatever you call it.
I'm gonna first try a fresh poppet oring and thoroughly clean off the poppet seal surface. If that doesn't fix my leak, I found a tiny split-ring lock washer that's just about the same OD as the spring and I'll use that to shim up the spring pressure a little bit.
Edit2:
The fresh oring and the shimmed poppet spring did the trick. Or at least something. I have the gun shooting in the high 290s at an LPR setting of 40psi and HPR at 225psi. Does this seem right? My LPR seems too low and my HPR seems too high. But otherwise the gun is shooting well.
There's still a very slight leak coming from the bolt port, but I'm sure it'll go away after a few hundred shots. If not, it's probably the front ram or poppet shaft oring and I'll just build up those glands slightly.
Actually that's pretty close to where they like to run. A little high on the HPR probably but I generally think 50-55 LPR is the sweet spot.
