Troubleshooting CO2 Regulator

I have an old Milwaukee Insturments regulator that is frustrating me. It is either all open or nothing with it. Even when adjusting with the needle I can get the bubble count to a reasonable rate, but it never holds. It may be days or hours, but sooner or later it either stops (most of the time or just pours CO2 into the system. High side is just under 1100 psi and low side is about 42 psi. Any lower an I get nothing with the needle valve wide open. I've cleaned the needle valve, beyond that I don't know what it could be. There seems to be a bit of play in the regulator valve. There could be no flow and if I push it in then it goes to maximum flow and I have to turn it down.

Does anyone have any ideas?

Thank you.
