No, you're attributing failures to ethanol. Barring you actually seeing the failure happening, you can't guarantee a failure is caused by something. I don't wish to nitpick, but that's part of being a mechanic And the reasons you repair them are more than likely due to user error, like leaving fuel in the saw for far too long and letting it do damage. That is user error.

So it's user error to want to be able to store stuff with fuel in it? Like the garden tractor... it sits all winter and fires right up every spring, on the same gas put into it late fall. Ethanol free gas doesn't really need a stabilizer... it stays fresh for a lot longer. Saws sit ready to go and typically fire right up.
I sure as hell am not gonna waste time siphoning gas out of the tank of the tractor to avoid the ethanol problem... and I am not gonna waste time and money (and cause environmental damage) by dumping gas out of saws to keep them from gumming up.
I got other **** that needs to be done, like cutting, splitting, and stacking firewood, and cleaning up the yard.
I'll just pay more at the pump for ethanol free gas and not have to worry about keeping things empty and replacing bad fuel constantly. Occasionally, one of the four stroke engines (like on the log splitter) might see ethanol but not for very long... it gets switched right back to ethanol free. The two strokes will never see ethanol when they are in my hands.
Stuff truly does run better with 10% more power due to the ethanol not being in the gas... 10% is a lot in a small engine... very noticeable. Hell, if you really want to see a difference, try doing a MPG test on your truck or car... you will see about a 10% rise in gas mileage when you run ethanol free gas through it.
Ethanol is a big scam... it is a waste of farm land... people should be getting quality food off of the land, not ****** corn or soybean crops that go to ethanol plants... It is clear that ethanol does damage to engines and parts related to them... try running E85 in whatever you drive right now and tell me that it works fine in the long term, I guarantee it will cause lots of problems. Special stuff is needed in order to work with ethanol. E85 compatible cars and trucks actually get worse gas mileage than their E10 running brethren.
Tygon fuel line is good, but ethanol still causes it to get hard and brittle in a fairly short amount of time. Regular rubber lines get hard and brittle too. I've seen it in many cases where the fuel line had to be replaced because of ethanol. Same goes for carb kits... lots of carb kits due to ethanol causing the diaphragms and fuel pump flaps to get stiff. Stuff turns into goo from contact with ethanol... fuel lines in chainsaws are notorious for this... try getting two new saws... mix ethanol blended gas for one, and ethanol free for the other... tell me which one fires up after a year or two of sitting with fuel in it.
If you really were an engineer, you'd be smart enough to know ethanol is a big problem with small engines, and especially with the older tractors, cars, trucks and OPE. Or maybe you're one of those idiot engineers that makes it so hard to work on these modern vehicles that I like to call pieces of ****. Can't replace something without removing a bunch of other stuff first.
