The vid linked below (no affiliation) reminded me that the significant chemist in my life has asked me to explain my aversion to ethanol fuel in anything that gets less use than the daily drivers. I haven't tried hard, or much, to research so I'll ask ... does anyone know exactly what happens at the molecular level when ethanol fuel goes bad?
Project Farm tests fuel stabilizers ... and says the crud that grows in carbs is a reaction between the ethanol and the "pot metal' / zinc-aluminum alloy carb bodies. Can this be explained in sufficient detail to satisfy a professional chemist?
Does this little item from the Classic Motorsports site help?
Does ethanol actually corrode metals and plastics?

yep, thanks, that led to this:

(light on the chemistry)
but adjacent search result was more what I was looking for:
