Idle problems on Propane powered engine - 72 Dodge Executive

[50YrOlNoob]

Blessings all,

I have done most basic maintenance on this vehicle. I changed transmission and engine oils and filters. I replaced spark plugs and wires. Replaced distributor cap and rotor and the last thing I did was to remove the Propane carburetor and cleaned it all out. It now manages to stay on with the gas pressed but will die in idle mode. I moved the "idle screw" and another screw noted on attached picture but no they don't seem to make a change.

Any advise or suggestions will be greatly appreciated.
