All my seasonal equipment, 2 stroke and 4, gets fuel during the last couple tanks of the season with 90-octane non-ethanol with "Marine Sta-Bil" in it.
If it has a fuel shutoff (big mowers, generators, tractors) I shut the engine off for the last time with the fuel shutoff to run the bowl dry. If there isn't a fuel shutoff (diaphragm carbs, etc), I just shut it off and leave it.
No more stale-fuel/clogged jet/ethanol problems ...
