Every drop of gas that goes into my small engines and outboard motor is ethanol free and has Seafoam in it. Before starting that regimen, I had a lot of trouble with gummed up carburetors, since, I have not had a single problem. I don't know if it is the ethanol free or the Seafoam, but I am not going to test to find out.

Ethanol-free is the way to keep a small engine happy.

I love Seafoam. It may be snake oil, but three or four times out of ten that I try it the carb straightens up quickly and it saves me the labor of tearing down the fuel system. May just be dumb luck, but I’m sticking with it.
