Default Re: Propane conversion

Yes, you're quite right. That's what I was trying to get at when I wrote this:

It would seem they would need an oil pump and injection system....if there is even a low ash 2 stroke oil available.
These HT engines are really kinda similar to what the Japanese brought to the USA in the late 50's and early 60's. Piston port 2 strokes are rather cheap and dirty design wise. The Japanese went with rotary valves and then to reed valve inductions fairly quickly. But never did they experiment with gas vapor
fuels like LP or Natural Gas. They also came up with oil pumps and injection fairly quickly in their
evolutionary process. These HT's are really similar to the model airplane glow plug engines. (of course they have a clutch, ignition system, and carb which refines them so they can run at different speeds and pull different road grades)
