I have tried propane in the past but never got good results. I even built a demand regulator but still could not get it to work. It may be time to give it another try. Nothing else seems to work.Another thought on the propane. If you find it works and your happy with it you will need to build a "demand" regulator because, as I think more about it, propane will free flow out of your carb air intake when the engine is not running. A demand regulator will supply propane only when the engine "sucks" air in (like it does for gasoline from a tank below the carb).
So to test the engine on propane initially you should probably turn the engine over and then slowly supply the propane with the needle until it runs and shut the propane off at the tank to stop the engine.
