Not a tractor, but close...
A Mitsubishi FGC 25 lift truck with an Impco factory LP system.
It has run flawlessly for many years with no PM on the fuel system at all.
Here lately it has begun to intermittently run really rich, burned propane stink, black around the exhaust, excess fuel consumption. There is no really noticeable loss of performance or starting problem. It might do this once a week, then run normally, seems to be worse in colder weather, but it lives inside the heated shop, so no real temperature differences.
It has always had a raw propane smell immediately after shutting the engine off. I attribute that to the engine coasting down with the spark stopped. There is no fuel cut off solenoid.
There are 3 main components, a high pressure regulator, a vaporizer, and the throttle/governor assembly.
I see a lot of Youtube videos on rebuilding the vaporizer. Looks simple enough.
Is that the most common area of trouble?
I have no idea where to start an official "by the book" diagnosis.
