I agree with Hammermechsnic man-I have 5 chainsaws, 2 string trimmers, hedge trimmer, pole saw, lawn boy 2 stroke mower, tiller, z turn, lawn tractor, IH LoBoy tractor, 3 generators, chipper shredder, mantis tiller, pressure washer, blower, 36" walk behind that all run on E10 with no issues. The FS80 stihl string trimmer is 24 years old and has had at least a hundred tanks of fuel through it all E10. Still has original fuel lines and never had the carb off yet. All 2 strokes get drained and run completely dry at the end of the season and the 4 strokes get filled up with no stabilizer. Everything runs fine.
Customers leave things too long and not stored properly and that makes me money.
I run a small engine repair shop and personally run 10% ethanol with no problems. Keep the fuel moving, keep it fresh. For 2-stroke handheld equipment, especially chainsaws, no older than 30-60 days. It seems most of my customers claim to run no ethanol fuel. I constantly see old fuel (turn yellow, dark yellow, etc.), and water in fuel. Use the fuel shut off valve after running equipment on occasional use basis.
This topic has been beaten to death, and been overblown. I clean lots of carburetors and very few of them are ever to far gone to bring back into service.
