I hate ethanol. My experience is pretty much the opposite of yours... I have had far too many occasions where a piece of equipment that has been sitting for a couple months simply won't start until I clean the carb, and put in fresh gas....... I am also not a fan of stabil...... I used it in my 2 cycle snow blower in spring for several years, and the following fall, when it was time to get it prepped for winter duty, it wouldn't start. At all. It would end up going into the shop before it would run properly again. So, one year, I didn't bother wasting the money on the Stabil..... I just filled the tank, and called it good. The following fall, the snow blower fired right up. I stopped using Stabil altogether after than, and a fair few of my problems went away.
I have also had issues of getting good gas, at the wrong time...... If you show up while the tanker is refilling tanks, all the crap that accumulates on the bottoms of the tanks gets stirred up, and ends up in your gas can. (this includes water getting emulsified rather well into the gas.) The problem persists for an hour or two after the tank (gas station) has been filled......
Of course, I have also had cases of good gas, clean carb, filter in the line, etc, and STILL having the carb screw up, and start causing issues...... Pull it, clean it, reinstall it, use the same gas, and no troubles again for the season.
Sometimes, I think grit just spontaneously occurs in the carb.
That's about the only explanation I can come up with, the fits all the circumstances.
