Thank you for the great write-up, Daniel. I am glad to see you are having an off the charts level of fun experience!
Regarding fuel, while most hit and miss engines can run on alcohol, I recommend strongly against it. Alcohol delivers a clear path to collecting water inside the fuel tank and inside the engine.

Good point Gil ... thanks for chiming in with that!
Perhaps one only needs to make a final run with one of the less hygroscopic fuels, after running with alcohol, to clear the system of any residual water, and store the engine away safely.
On the other hand, don't we pour alcohol into our fuel tanks to get any residual water to be absorbed out of them?
