HW100 Regulator issues

Guys,

Looking for input on a problem child.

HW100FSB in .177 full power version had problems with regulator creep and I volunteered to do a reseal and tune. I've been in them before so no problem right? This one is bypassing the regulator completely with no difference when adjusting the tensioner screw. I have a gage into the reg port and as soon as i screw the air cylinder in it goes to cylinder pressure. Anyone have some insight? Bellevilles are stacked. (())(())(())(())
