Fuel stabilizer is an acceptable alterna- tive in minimizing the formation of fuel gum deposits during storage. Add stabi- lizer to gasoline in fuel tank or fuel stor- age container. Follow the mix instruc- tions found on stabilizer container. Run

engine at least 3 minutes after adding stabilizer.

Craftsman 40:1,2-cycle engine oil (air cooled) is already blended with fuel stabilizer. If you do not use this Sears oil, you can add a fuel stabilizer to your fuel tank.

•Replace spark plug with new one of recommended type and heat range.

•Clean air filter.

•Check entire unit for loose screws, nuts, and bolts. Replace any dam- aged, broken, or worn parts.

•At the beginning of the next season, use only fresh fuel having the proper gasoline to oil ratio.
