I don't care for ethanol fuel in any of my small engines, except my generator. With non ethanol being over three bucks a gallon, and ethanol fuel being a little over two bucks a gallon, the difference can ad up quickly in an extended power outage. Plus I have to make special trip to go get non ethanol fuel, which adds to the price. I can also connect a hose to fuel rail on vehicle and let fuel pump refill generator, or gas cans. After I run the ethanol fuel in generator, and outage is over, shut off fuel to carb, run engine dry. Then I disconnect fuel line from carb,and drain remaining fuel back into gas can, which is then used to refuel vehicles vehicles when needed. You can buy fuel line quick connectors of ebay, which makes it easy to disconnect fuel line from carb. Just don't buy the ones with auto shut off, or you won't be able to drain fuel from generator fuel tank.
