Hi Insane,
I have a Saito 1.50 that I ran on gas woth a C&H ignition, a Rimfire plug and a 16:1 gas

il mix. The Saito carb worked fine, Just had to turn the needles in quite a bit to lean it out.
For info: I had run the engine on glow fuel with the C&H ignition because I had trouble with it throwing props when I tried to fly it as a glo-plug engine. Tried the gasoline as an experiment. I used 95 octane pump gas and Klotz synthetic oil.
I have a NIB Saito 1.80 that I've been toying with the idea of running on gas too, also with the idea of saving weight.
Cheers,
CR
