I have been using non-ethanol gas for my saw mixes, about 40:1 ratio. I have 2 Stihl 026 saws. One is about 25 years old, other 15. Newer one runs fine on the mix. Yesterday, the older one (which I had the gas line replaced 1 year ago) was running fine but started to stall out like it was sucking air. I poured the mix out and put in some of the pre-mixed 50:1 stuff I happen to have. Now, it ran continually but at about 15% less speed. No power, basically. So, I poured half that out and put in half my 40:1 mix and the thing ran like a champ. No sucking air symptoms and plenty of power and speed. But the pre-mix stuff is $20 per gallon. So, now what? Shoot for 45:1 and try that? How temperamental are these things?
