Air:Fuel Help. Cannot Get it Rich

Up here we call it gasohol. They mix ethyl alcohol into the gas to increase the octane rating of supposedly chitgas so the oil companies can sell more gallons of gas from the same amount of crude; and the dollars keep rolling in for them while the MPGs of the newer cars go up; those greedy bums.
So anyway you gotta watch the pumps; if there is alcohol in the gas, the sticker will be on the pump, saying something like "may contain up to (x) percent alcohol", x being 10 or 15. You may know it as oxygenated fuel, cuz they like to hide stuff.
E85 requires almost twice as much fuel to make the same power, and when you jam it thru too-small jets it ain't but half big enough. E10 and E15 are not that critical but you still need to upjet. That happened to me one time on a roadtrip; I couldn't even cruise on the primary jets, I had to stop on the shoulder of the interstate and upjet. And the first guess wasn't enough,nor the second.
