I am really ignorant about propane power, so go ahead and laugh and scoff.
It seems to me that the throttle controls the amount of propane that enters the system, which immediately becomes a gas (if not already in that state before it gets to the throttle). What controls the amount of air that mixes with the propane? is it just a function of how fast the engine is running and pulling more air as it turns faster?
There was a thread here about starting a small engine with propane, and then there was a thread about squirting starting fluid in the 455 to enable it to clear an intersection if the fuel delivery system failed.
So I couldn't sleep last night and one thing that popped into my head was, if the fuel delivery system failed on the highway, and I had the parts to cobble together a line from the propane tank to the carb, could I get a few miles down the road to the next off-ramp, or would I run the risk of burning a valve or two due to a too lean mixture?
