NormK and Mowerfreak, I forgot to ask a question about the fuel side of the 2 Stoke Engines. I remember my dear Dad always saying that you should always 'turn the fuel off and let the motor run until it stops by itself'. Knowing your experience, would you say that this would still be the case, or is it better to turn the fuel off and stop the engine? I would appreciate knowing the better way to look after both our Lawn Mower and the Edger in the future. Thanks again. Sherrie.
