What I do observe is the residue in my carbureted engines float bowls and carb body passages when corn gas is used. I do not have this residue when using non-ethanol gas. Same fuel tanks, hoses, and so forth. Given these engines are all older (before the ethanol fuels were mandated to create a new tax generating commodity market) I'll continue to use ethanol free fuel.
I do experience improved mileage and throttle response from real gas too.
Hiya,
I would bet most likely, that residue you see is from the ethanol loosening gum, etc. in your tank, that is then getting run through your engine. Even if you empty your tank completely, there is fuel residue that remains, and it will eventually build up in your tank.
