Travis, some of the Kawasaki engines are really great and long lived. I have their 2 cylinder engine on a Ferris Zero turn mower, water cooled version. 26 HP don't remember the displacement but it's 13 years old now with 2105 hours on it. So far no problems and I should not say that because now it will explode. Anyway, changing oil and filter every 50 to 75 hours over its life I'm sure has contributed to its longevity. Putting in new spark plugs every year or 2 helps with the starting. I should check the valve adjustment too but will try to remember to get to that this winter. GC
