Not other than the WheelHorse and the generator. Or the old Ferguson TO-20. Or about a dozen chainsaws, and a couple of trimmers - you could count the diaphragm pumps in those as mechanical. All run on 87 E10.
Newer two stroke stuff have diaphragms that are made for ethanol. Older stuff (like the early 90's trimmer I have) do not and the diaphragms get really hard.
Make sure you shake two stroke small engines before you run them if you run ethanol. A little water (condensation) can make the ethanol separate from the gas, ethanol goes to the bottom (where the pickup is) and the oil stays with the gas... so then your two stroke is running on straight alcohol with no oil.
Once it separates out in my '46 John Deere B it will not run on straight alcohol so I have to drain it from the system before it will run. My A-C's throw more fire out the exhaust at night but will burn it, I would probably need to play with the timing if I was to run it very much.
