I just bought a complete CO2 system at my local HB store. It was a Foxx kit. I filled the CO2 tank and attached the regulator. I turned the adjusting screw fully counterclockwise and opened the CO2 tank. The tank pressure gauge jumps to about 620PSI, but the output pressure gauge stays at zero. I can't get any CO2 to blow through this thing. Nothing blows out of the relief valve either.
Do I have to do something more to this regulator?
