My neighbor calls and asks if I think I can get his other mower running. It's been sitting under a tarp over the bank where he mows by the water. He put fresh fuel in it and a new spark-plug but no fire. I asked if he checked for spark, thinking the magneto is rusted up. He said "I don't know how to check for spark" I contained my laughter. We check and yes there is spark. Next I start in on the fuel system. Hmmm maybe we should turn the gas valve to the "on" position. Fires first pull. He is a retired electrical engineer. How people like that made a living I will never know.
