I live a hundred miles north of NYC, and so am still within the radius of mandated E-10 fuel.
When the ethanol fuels first showed up here years ago, I watched the guys who make their living with carbureted engines, to see how they dealt with it.
These included the lawn mower guys, the brush cutters, loggers, etc.
The first couple of years they struggled, and were seemingly always rebuilding carbs.
Then they shifted to Stabil, SeaFoam, etc , for several years.
Currently, (for the last few years) they've shifted to using high test gas.
They've found it consistently more stable than regular and much less problematic, and simpler than using an additives.
But still anything in their gas cans more than 3 weeks gets dumped in the tanks of their trucks and cars.
Their trucks and cars are fuel injected, and they found exactly what you did, Bruce; the fuel injection isn't bothered by crap gas, self cleaning and self adjusting to whatever the fuel has morphed into.
Lazy sod that I am, I've followed them all along this path.
And whenever I travel further north, I bring gas cans with me, as about 30 miles further up the line non-ethanol gas can be purchased; the bikes like that fuel the best, I presume it's the extra BTUs.
And the high test is what goes in the tanks for last fill-up of the season, no startup issues in the spring.
Best-
