70 tossed out its spark plug.
Tonight I was mowing with my old 70 for a hour or so and it ran great as always. I was minutes away from being done when it lost power labored and then bang! It spit the spark plug out of the head. The plug was tight and the head threads came out with the plug. I have never seen that happen before. Any ideas as to what happened? Was I working it too hard? Or maybe the threads were stressed from old age? Fortunately I have another head I can swap out but I sure would like to know what happened.
