My cub cadet was running fine and it started to sound like it was running out of gas and quit. I discovered I had no fire at the plug tip. Now I had just put in a new plug for the start of the new mowing season a day earlier. I've narrowed it down to what I think is the coil or the black box that's wired to the coil that mounts on the outside of the motor and close to it. I have also noticed that the one relay closest to the coil isn't clicking either. However I do know the relay is good. What's everyone's thoughts on what my problem could be or what I should do to next? Thanks
