There is a learning curve for E-85, and it will HATE a cold engine. Users have reported that the engine must be fully heat soaked to see full power/efficiency. Makes me wonder how much of the stuff "globs" up on the walls of the intake runners until the engine heats up some, and if any makes it's way past the rings and into the oil during the warm-up period......Cliff

From what I have gathered so far the tuning window on the main jetting is pretty wide. Methanol was the same way, getting heat in the motor was important for performance...and hard to do on cold days. I will be getting all my carb parts thru you, thanks for all your help with this engine project. I may run it on good gas first, then move to E85 later.
Would blocked heat riser ports amplify the cold bloodedness of an engine on E85?
It was pretty popular as a fuel at the circle track in our division, till the series came out with "spec" fuels. 91 no ethanol ($4)/gal and 110 Sunoco ($8/gal), and banned all other fuels, exotic and pump.
