euh Don, i think its just the opposite… 85% Ethanol and 15 % gasoline… E100 = 100% Ethanol
Try M100, drag fuel ( Methanol Aka woodalcohol )
The stuff that makes your dreams come true
AFR for E or M is different then gasoline ( methanol 6.4:1 = 1.00 lambda )
So using a carburetor would need adjusted nozzles for the greater flow of fuel, and in case of injection it needs larger injectors.
Old engines indeed needed the alcohol preheater, but new engines do perfect without it… I take it up to CR 14 to 1…
