I just hooked up a new MA957, and it's acting incredibly bizarre. I've previously had several of these that ran for years with zero issues, then I was away from the hobby for a while... here's what happening:
I completely turn off the cylinder (CW) and connect the reg (yes it has a disc), then I make sure the needle valve is fully off (CW), and the knob on the reg is fully off (CCW)... when I open the valve on the cylinder, the right-side gauge climbs until it is pegged... I cannot set it to a value (e.g. 60)... here's where it get really weird: after I shut the valve on the cylinder off (tightly!) the right-side gauge continues to climb! If I open the needle vale, the gauge starts to drop, but as soon as I close the needle, it starts to climb again like the cylinder vale is cracked open..
If I pull the reg off and spray soapy water on it, there is no leak. If I connect the reg and crack the tank valve open for a second, and close it again, the gauge climbs until it pegs... I'm baffled, any thoughts!?
