15% ethanol destroys 2 cycle.... good read.

I was in the Dr. office reading a bass fishing magazine. I came across this article. There was more to it, I just copied the short and sweet part. Kinda scary.

They didn't mention adjusting the injection systems or carburetor for increased fuel flow. Alcohol burning requires larger jets (more fuel flow), many people do not realize this and try running engines with "gas" sized jets.

Restricted fuel flow results in a lean air/fuel mixture resulting in over heated, damaged engines. A person can cause the same damage by running standard gas at too lean of a air fuel ratio.

Small engines like chainsaws can handle more ethanol but need carburetors adjusted accordingly. Alcohol is corrosive to older rubber fuel lines and other components. It is wise to drain a saws fuel tank for storage and remove carburetor gas by idling the saw until it quits.

A few years ago there was a saw modified to run E85. The person who did the work reported the saw ran good but had short amount of run time. To burn E85 requires nearly doubling the fuel flow into the engine. Resulting in a tank lasting about half the normal run time.

A correct functioning engine is all about tuning the correct air/fuel ratio.

And regarding the supposed "renewability" of the resource, let's then look at what it takes to grow corn at the scale of ethanol. Very detrimental. No nutrients put back into the soil, an immense amount of chemical used, which destroys the land, as opposed to enriching it, like proper farming does.

Soooooo, your saying corn grown to produce ethanol ruins the land, but if it's fed to cattle it does not? What exactly is your idea of proper farming? Ethanol is a bad thing for occasionally used small engines, but don't tell me growing corn destroys the land.

I never said it was good when fed to cows. Massive monocropping is a bad thing altogether. They can't even digest it, cows are ruminants, they're meant to eat grass, not corn.

Because of the methods in which we force corn to grow, aka massive amounts of synthetic fertilizer and pesticides, we now have a nice big ol' dead zone (where nothing can live) in the gulf of Mexico the size of lake Erie: Gulf 'Dead Zone' This Year Predicted To Be Largest In History. Where does all of that goodness go? Downstream! I have heard and read that during times of supposed "fertilizing" and pest control, people in cities along the rivers are advised not to drink straight tap water.

And beyond all of the downsides, the only way that corn is an economic reality is that we all pay for it, it's subsidized.

Those of us in the know must contact our Legislators about this very serious problem with ethanol in our gas. The suits in Washington haven't a clue to what this stuff does to small engines, and could care less. But we here in this household rely heavily on a 2 cycle engine to heat our butts!!
