10lb tank with the Milwaukee MA... whatever regulator (with everything attached) that everyone has. 
I have had my Co2 tank running on and off for about a year a half with no issues. A few days ago I noticed the bubbles were coming out VERY VERY slow so I figured I was running out of CO2 but I still had pressure, 50+. I tried opening the needle valve all the way and the rate of bubbles did not change, even when I tried to closing the needle valve it continued producing bubbles (slowly). I tried closes the valve on the regulator and the right gauge went up but when I reopened the valve the gauge did not go back down. I removed the whole regulator from the tank just to make sure my pressure gauge was not broken and sure enough when I crack the valve open CO2 comes out. The right gauge still did not go down so I thought blown right gauge no big deal but when I reattached it to tank it went back down. I'm out of ideas & this is my first time dealing with CO2 or regulators, any ideas?
