The PDF I linked to explains better why some two cycle engines are failing with this stuff. It relates to air-fuel mixture.

Here is a rock solid tip on adjusting the "high rev" screw on your saw carb.
DO NOT adjust it so your saw is screaming fast, this means you have leaned out the air fuel mixture and you are going to burn up your cylinder/piston much faster.
Adjust your "high rev" screw on your carb until it leans out then bring it back so there is a slight "gurgle" in the high revs. This means your running a bit richer fuel mix and it is what you want.
All above has been learned the hard way.

Bill, I guess my saving grace is that I have newer saws. I traded my older ones in for lighter and more powerful saws. The other factor is I am kind of whimp. I can last almost a tank of fuel and I am done for a while. I'll ask the guys at the saw shop. They have been doing this a long time and seems to be up on things. If anything I am more a recreational chain sawer, if you can call it that.

Interesting is the 10% ethanol. How big is the fuel tank? That is not much ethanol. What does it call for in adding oil? 10% oil increase is probably negligible for all practical purposes.

I have a off brand weed whacker, it is a 36:1 ratio. I will use my Stihl mix (50:1) and then toss in some extra oil. Close enough, it smokes a little but still runs.

Thanks for the PDF, it was a interesting read. I think the biggest performance booster is keeping a sharp chain on the saw. I watch my chips, when they start looking like saw dust, I will change by chain.


I like wood heat, house runs around 75 Degrees with stove chokes all the way down. We added to the house insulation a few years back and it pays.

The energy resource people will pay about 80% of the cost. I need about 2 cords a year. When it is not so cold, I use a heat pump.

Last year I help some other people by giving them about 8 + cords of wood.



Again thanks for the PDF, I will ask the guys at L&L.

H.

Just asked L&L, guy there said, "Just don't leave it in your saw/can for longer than 60 days and keep the oil ratio the same."
