Being a spreadsheet junkie, I love numbers. Just a friendly piece of advice, watch your decimal point placement. Throwing in a "mm" & " here and there could help. Very much enjoyed reading all your posts on your efforts to build your engine.
I don't know anything about your engine, or for that matter, not much about 4 cycles, but having followed Bob's for 6 years, I read a lot about jetting for various fuels. Alcohol burns at about a 6 – 1 ratio, and the information I have read here on Bob says, generally, that a .052" main jet is about right, give or take. Running a .062" with E 85 would seem a little big, maybe?
Mixture ratios of E 85, as was mentioned, would have more of an effect on jetting than any concerns you might have about octane rating. EFI can handle those varying mixture ratios, fixed jets can't.
Another concern; what do you suppose the octane rating is of the gas they mix with alcohol to make E 85. Would that gas retain its original octane rating? Knowing that you can't run regular gas with a compression ratio like yours, what would be the effect with the E 85? Would the gas still be detonating?
