Not sure if it’s a perfect solution, but I run high-octane (93) fuel in all of my small-engines, including my lawn tractor, snow blower, pressure washer, ATVs and UTV and I add Sea Foam with every fill-up. Although I hate the idea of ethanol for all the reasons described above, it seems to be working well.

no its not. it still has ethanol, and now your engine is not firing where it should because the octane is too high.
