When I winterize my small engines (lawnmower, generator, etc) I typically turn off the fuel valve, run them dry, drain the carb, and store them away. I got to thinking about the residual fuel in the gas tank, fuel lines and fuel filter. My little Honda EU2000i has a fuel pump and it is hard to get every last drop of fuel out of it. Sometimes it can be temperamental after a long storage.
What about adding a little (1/2 cup?) Coleman fuel to the empty gas tank to flush out the lines, pump and filter?
Drain the tank and run the engine dry of gasoline. Put a little Coleman fuel in the empty tank. Start the engine and run it no-load until it runs dry (probably only about 5 minutes or so). The Coleman fuel is quite volatile and any liquid left will evaporate out of the system in a few days. This would leave a clean & dry fuel system for long term storage. Coleman fuel also has a rust preventative in it, so that should help long term too.
I haven't actually done this yet, but I remember my dad using Coleman fuel in a pinch to finish the lawn when I was a kid. Mower seemed to run ok.
