Fuel stabilizer is an acceptable alternative in
minimizing the formation of fuel gum deposits during
storage. Add stabilizer to the petrol in the fuel tank or
fuel storage container.
Follow the mix instructions found on stabilizer
containers. Run engine at least 5 minutes after adding
stabilizer.

engine oil through the spark plug opening. Slowly
pull the starter rope 8 to 10 times to distribute oil.
Replace spark plug with new one of recommended
type and heat range.

Replace any damaged, broken, or worn parts.
At the beginning of the next season, use only fresh
fuel having the proper petrol to oil ratio.
