Thats all fine and dandy. I'm simply posting my experience with E-10 fuels. Not only do I have 8 Vintage snowmobiles running fine on E-10, I have bought, fixed, and sold 10 others running fine on E-10. I have a Strikemaster from 1991 runs fine on E-10. All my lawnmowers thru the years, my boats, my dirtbikes never have had any trouble relating to using E-10 fuels. I actually rebuild these things, maintain, and tune them.
I still state that the problems stem from poor maintenence rather than the fuel type. You guys can run around screaming the sky is falling if you wish. It just isn't so-
