Im trying to get a straight answer on using todays 10% or less Ethanol added fuels. A little background info on myself. I am a 40 year plus Certified Small Engine mechanic.
Im a firm user of Non Ethanol fuel in ALL small engines and I have been lucky enough to find it locally. A few years ago I needed 2 stroke fuel for some repair jobs I was doing and I purchased the 87 octane 10% Ethanol. I got it from a quality gas station that does a high volume of fuel sales. Moving on I mixed my fuel and put it in a chainsaw and the saw ran as it should. The customer came to pick it up about a week later and it would not start. I replaced the fuel with Non Ethanol and it started perfectly. Why would fresh fuel a week old not start a chainsaw? My guess would be a high energy ignition system is needed to burn todays fuels?
