last time I went wheeling, my regulator (the big silver knob you turn) froze up and wont budge. It wont move, with the main, black screw valve open or closed, it doesnt matter.
As you can see, there is still pressure in the regulator. I can't bleed it out, since the knob wont turn.
Has anyone else experienced this problem.
According to my estimates, I should still have 7-8lbs of CO2 in the tank. I have only tried turning the knob with my bare hands.
