The Kawasaki engine on my new 2004 Bob-Cat WB (which I love) has become extremely hard to start, it takes me 20 minutes to get it started. Once it is started it runs great and it starts on the first pull when it is warm. My thought is that perhaps the magneto a.k.a coil has failed. The engine only has 50 hrs on it. I am taking it to the dealer tommorow.
