Matt,
"If you burn "Methanol" get you wallet out because 1 gal. is probably 5.00 and you will go thru twice the amont/hr as gas. If you "pickel" the carb after each use corrosion will not be a problem."
The problem here is where you get the numbers. If you purchase methanol or ethanol from a chemical supplier, yes the price is expensive. If you purchase fuel ethanol much of it is imported and the duty is quite high, so again expensive.
If you produce it, it becomes quite cheap, even considering your labor cost. Also ethanol does use more gallons of fuel for the same amount of work, but only if the engine is not retuned for ethanol. An ethanol tuned engine can have the same economy while producing more horsepower.
Or so I have read. There is a lot of information out there, much of it FUD. Seems the big issue is ownership. You can own an oil well and be in control of the market, but you can't own the process of making ethanol. Moving to ethanol means that *anyone* could compete in the fuel industry, not just the owners of the oil wells.
But now I am off track from running a Cub on ethanol. More reading seems to say that the carb, if aluminum will be fine, but if any magnesium is present, it will disintegrate. The rubber parts should be ok if they have been produced in the last ten years. Cork apparently, is terminal in ethanol. Or so I believe. I think I really need to soak a carb to know for certain.
So jetting (bigger), float level(it floats higher), and timing(needs more advance) seem to be the things I need to look into.
I just might give this a try this summer. I can buy plenty of E85 in town to test with. Thanks everyone!
