Have a Coleman Powermate portable generator with an 11-hp Tecumseh engine. I bought it new, but didn't get a chance to run it until this past storm. Ran great by the way. I'm getting the generator ready for long-term storage. The manual says to drain the fuel and to place a teaspoon of oil where the plug is and pull to max compression. I did all this, but I have one question. There's a very small amount of fuel surrounding the fuel intake. It's like a small saucer around the fuel inlet, so there's maybe a teaspoon of fuel left. Do I let that fuel evaporate, or is there some trick someone could share? Thanks in advance.
