The ethanol free gasoline should be easier to get a stubborn engine running on. The ethanol in gasoline does not burn well or ignite well in our low compression engines.

Had the existing ethanol-tainted gasoline been in the tank a long time? If so, it may have absorbed enough humidity or condensation inside the tank to have the ethanol be saturated, resulting in the fuel separating into water, saturated alcohol, and gasoline.

So the water would be on the bottom of the tank, and be drawn in and be in the fuel pump and carburetor float bowl.

Drain the carburetor [remove a main jet and let drain] catch what you drain out, and put in a clear glass jar, let it sit and see if it is homogenous, or stratified into layers.

Will the engine fire on starting fluid ? It won’t run long, but should fire. Often ‘bad gas’ causing a no-start situation is not the gas, but an ignition problem.

Hope this helps.
