Why does it keep leaking. I'm on my 3rd oring to get a seal. I grease the groove then put in the oring and grease. When I gas it, it's quiet. Fire it a few and listen and it starts to leak until it's fired again, then slowly starts to leak again, repeat.
Also, unrelated, why would I have a bunch of grease inside the frame at the back of the solenoid? Does it vent or something
