I got stuck out in the rain lastnight, i took my rifle apart to ensure I got it clean and dry. I took everything apart minus the plenum plug, and the bottle adapter. Re assembled and now it is "bleeding" air out of the tranfer port at full steam ahead. Almost like there is no reg installed. The reg is in. Humma gen 3 with 9 washers stacked according to their instructions. Any help is appreciated. Cheers
