Re: Propane conversion
Jeeze i didnt realize there were so many Nutmeggers in here. I wanted to do this with a 2 stroke myself but i was told making a oil injection system would probably cost more than the engine....
But as far as 4 strokes, i feel like this would be simple. Im thinking of the mythbusters episode where they ran a carbeurated car just by puting a hose of hydrogen near the carb. If you just wanted to try out the theory you could hook up a little coleman tank and just turn it on a little at a time untill wot worked. If that worked well you could figure out some sort of needle valve setup.
I would think the intake charge would be much denser if you mounted the tank upside down, maybe more moper than gasoline?
