I don’t have any of the ethanol problems people talk about. I don’t use any stabilizers, or additives. My stihl weed eater gets out away for 6 months and I have no problem starting when I get it back out and it’s 9 years old. My generators sits for the same amount of time and no problems there either. My 51 (with a 59 235) is fuel injected now and does well with ethanol fuel. My Mercury boat motor is the only thing I own that doesn’t like ethanol fuel.
