As I recall, ethanol does fare slightly better than propane, though it is only about an 1.1:1 advantage, and propane is easier to meter and mix.

Hi

Good for you .. it was the first fuel I ever tried. I lived at 57 degrees latitude by then .. that's where you have to kick the polar bears back out of your garage if your left the door open one day. It was a total failure...

Regards
