Iv been having problems with my 17 horse Kawasaki lately. If I shut if off hot, it wont restart. If it dose restart then it will run on one cylinder for about 3 minutes till the other kicks in. Well the other day I got finished using the mower. For some reason I wasnt ready to put it back on the trailer yet. I wanted to be able to restart it, so I let it idle wile I did something. I was across the yard and I heard it shut off all by it self. I thought great now Ill never be able to get it on the trailer. I went over, and pulled and pulled. This time it didnt even fire at all. I went off and mowed some lawns with just my ZTR, and left the walk behind mower on the lawn for the rest of the day. Later on that night I recruited a buddy of mine to help push the mower up on the trailer so I could bring it to the doctors the next morning. So the next morning I dropped it off in the pouring rain. My dealer is very good and usually takes me in right away to get me going again. I have Bobcats so I hardly ever bring it to the dealer for something broken. I came back the next day, and I asked if they had diagnosed the problem. He said ya. I said did you fix the problem? He said ya. Then he went on to say that some guys need some common with there sense. See, this guy never just fixes your mower. He needs to give you a bunch of baloney as well. Apparently they went through the whole machine, checking this and that. Then one guy suggested if it had gas in it? ..Guess what?? Needless to say, I had to pay for the labor. That was the most expensive quarter of tank of gas Iv ever purchased. To top it off, I thought he had filled the tank up. I ran out of gas on my next lawn again. Then to make matters worse it wouldnt restart because it was still hot.
