Well, my original idea was to convert a weed wacker engine to an RC enginge and hehe.. making that then an ethanol engine.

That is of course the ruff idea of it.

If you know as much about it as I think you do... you obviously cant use a glow plug system for ethanol. However I could take a simple OS engine and dump out the piston and put a spark plug in. But that isnt likely what I will do. Id like the final engine to be atleast a 1.74 cu in. I am still researching this all so I dont have a real answer as of yet. I dont know the ignition on a weed wacker so i cant really say about that.

I do know however that I can take a gas engine and do what is necessary....

Hopefuly I can run a full blend or atleast 95% ethanol.
