On the ethanol debate...
Not defending this or trying to say it is good in any way, but the problem is not the ethanol itself.
There were saws test run here on E-85 a couple years back.
Biggest problems I find with the E10-E15 is that the oil need to mix, it can't be stored and resetting of saws more frequently as fuels change.
The aggressive stuff in fuels is not the alcohol. Finding oil that mix with Alcohol is not always easy.

It would be better to use good quality fuel with good oil in proper ratio. Much friendlier to environment.

That right there is why I run my Klotz 200 or 100, it mixes with ethanol, methanol etc and stays mixed. Even though it dont have rust inhibitors for thos high humid areas.
