so I've used ethanol fuel in my saws for a long time. Since my stable has grown and so have my cc's, I figured that I would get some non-ethanol fuel to give to my lesser used saws to save some internal rubber parts. I was in Lowes the other day, went in there for my Dremel, and I saw some Husqvarna non-ethanol fuel in the quart container. Look at it, 93 octane, same as I use, and figure I'll buy it to put in my big saws that I don't use that often. Put it my 066 and it ran real rich. To the point of stalling out the engine. Now I have got my saws tuned very well, I think, and this was kind of unexpected. So I grab my screwdriver and I tune it to where I think it should be. Now, it didn't take that long, but it sure ate up some fuel. So I was thinking it might have been out of tune. So today I put it in my 460, and the same damn thing happens. This time I know it's not the tune because I was just cutting with it and it ran like a raped ape. I couldn't even get it to tack above 9,500 and that's with the high screw all the way turned in. I don't know what to think. Bad fuel? I know that people run their saws on non-ethanol fuel, but this has got me worried. What the f$&@ is going on? Anybody?
