Non ethanol gas

Mowing the yard is not a task I mind doing as long as I have a mower in good repair and gas in the gas can.  And that can be harder than you might imagine.
We took our mower to the shop last year, and the guy adjusted the carburetor for us.  He suggested we buy non ethanol gas for the mower.  Usually we mow into October or November, and then I usually try to start up the mower when we have a mild day in December or January.  We usually are mowing again by March.  With the non ethanol gas in the mower, the mower started this spring on the first pull.  I hate paying such a high price for gas, but I'm pleased that the mower is running smoothly.

Have you had problems with ethanol gas in small engines?
