Ed, does this work mainly with 2-strokes? I have mostly 4 strokes in my fleet and would love to convert them to gas but without having to add the weight of ignition. I do have a ST S75 that I think I will try your mixture with. Here's a question, seeing how the ethanol in gas is bad for our little motors. What about using Coleman white fuel? It seems to be a growing trend as it is 100% unleaded fuel. It is a little more expensive than pump gas, yet less than half the price of nitro.
