Have any of you guys out there had the magneto aka coil, on a Kawasaki engine die early? I have a really hard time getting the 15hp engine on my Bob-Cat (which I love) started when it is cold. When it is warm, it starts on one pull, and it runs really smooth, so I think something in the ignition has failed. I am planning to take it to the dealer next week. The engine only has 50 hrs on it.
