Manufacturers are recommending draining the fuel tanks on equipment with small gasoline engines and running the fuel system dry.
Stihl recommends: “The fuel tank should be emptied. Run the carburetor until dry (Warning! Do not operate throttle; run equipment in idle until the engine stops!)”. This is a great tip because 2 cycle engines rely on the oil in the fuel mixture for lubrication – no fuel/oil mix in the crankcase – no lubrication!
Generac recommends: “To avoid engine problems, the fuel system should be emptied before storage of 30 days or longer.”
Honda recommends: “Before storing the outboard motor for a prolonged period, we recommend that you remove the fuel line connector and operate the engine (4 stroke) at 2,000 to 3,000 RPM until it stops”. The owner’s manual also provides instructions to drain the carburetor bowls for storage. (taken from the Honda BF50A owner’s manual).
