Al, I had to replace a lot of fuel lines in the gasoline powered stuff that I have because of the ethanol.
Now I drive the 25 or so miles one way to get ethanol free gas.
I run 100LL fuel from the local airport in 2 of the 3 chainsaws, and e-free 93 octane in the one where the timing can't be adjusted.
Even so, I still use Marine grade Stabil in the gas and put in an ounce or 2 of SeaFoam per gallon as cheap insurance.
