I have a craftmans 917.274400. I have a dead battery but jump started it a few weeks ago and cut my lawn. The next time I went to start it, it would kick over at all. So I changed the spark plug, and drain the existing gas thinking that it might be bad and it still won't try to turn over. I know I have electric up to the spark plug because I test it. It just spin and not even a sound of it trying to start. Any ideas.
