Most parts being made now as replacement have the ethanol safe rubber in them, and hoses can be easily replaced with ethanol safe materials. I'm in Illinois, we have the same issue, all of our gas is 10% ethanol, too. I've been running it in mine without any issues. I have heard of issues with the aluminum in the carbs, as it is corrosive to aluminum, and some issues with corrosion in the feul tanks, but at 10%, I don't think it would be an issue.
