hey buddy, yes the manual does say the 1/4 turn CCW.. but thats a generalized approximation. Close the reg ALL the way shut after you degas.. Then regas the gun, to 4k+. then SLOOOOOWWWWLY start turning ccw. i'm talking passing a kidney stone slow. And you'll find you can start as low as 1400-1600. This is how i do it. I've had creep, but, i've noticed it's AFTER i've set to a pressure, shot for a while, and change pressures.. Since this last degas, regas, reset. Mines solid at 1800, NO creep over, The AV reg does seem to reset slow, You shoot, it drops, takes about 30secs to truly equalize to set pressure. Try degassing, Go ALL the way Clockwise till you can no more. Regas, Open slower than cool tar flows.
let me also say, it can take a second for the reg pressure reading to catch up to the adjustments youre making, Turn CCW a bit,then stop... wait. it should equalize in a little. once it does, move up from there.
