This seems to be incredibly area dependent.I have not had any trouble even with E10 fuel as long as I add Sta-bil to it. I have gone 9 months without using the fuel and it works just fine. Never had a carburetor rebuild in over 40 years. My main problem was the bar oil pump on my Stihl saws.
Around here, even E0 left in a carb over the winter will require clearing the carb when you go to restart.
I run E0 with a double dose of Stabil in both generators, the pressure washer, and the riding mower. All have a fuel shutoff, all get the carbs run dry after every use because I have no idea when they'll be used again. Might be tomorrow, might be next year, and I don't want to have to try and keep track of it and come back to it later if it's been awhile.
I'll be trying another fuel stabilizer that was recommended here next time I rotate fuel. PRI-G, I think.
