GTORAGE WARNING ....... it To avoid engine problems, the fuel system should be emptied before storage of 30 days or longer. Follow these instructions.
Never store engine with fuel in tank indoors or in poorly ventilated enclosures, where fumes may reach an open flame, spark or pilot light such as on a furnace, water heater, clothes dryer, etc. 1. Run engine until fuel tank is empty and engine stops due to lack of fuel. 2. Disconnect fuel line at carburetor or fuel tank. Be careful not to damage fuel line, fittings or fuel tank. Drain any remaining fuel from the system. It is important to prevent gum deposits from f{)rming in essential fuel system parts such as the carburetor, fuel hose or fuel tank during storage.
Also, experience indicates that alcohol blended fuels (called gas )hol or using ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel syster i of an engine while in storage. t WARN,NG t Drain fuel into approved container outdoors, away from open flame. 14
