For you guys that have been running E85 for a while, how are your carbs holding up with corrosion? I worked on a blow through Deamon carb yesterday that has run E85 on the street for a while and it was full of white powder corrosion. I am working on a similar combination for my cuda and am worried about long term corrosion issues. Also if you buy E85 at the pump, the alcohol content may vary, my buddy who runs circle track buys E85 from the regular race fuel distributor so he can be sure of the formulation.
