Default Re: I'm running E85/Ethanol(when should I expect something to go wrong)

Check the carburetor and fuel valve in about 6 months.
E85 attacks aluminum and corrodes brass. It will also attack the white plastic that the float is made out of.
It will also attack most gasoline resistant rubber seals and gaskets as you all ready have found. Be sure to check the black Viton rubber tip on the float needle. I have seen them swell up to twice original size and the float mechanism cannot maintain the proper fuel level in the float bowl. That was with E10 and a cheap chinese carburetor rebuild kit.
E85 is worse.......
