I had a 3 bag system with the 5 HP Honda. I sold it and bought a hyd dump system with the kawasaki. I much prefer the Kawasaki engine over the honda. My Honda died in less that two years. It was replaced under warranty , thank goodness. The air cleaner on the kawasaki is much better than the honda, and I think dirt killed mine. Northern tool had a honda that I was thinking about buying until my local dealer helped me out. The only difference was about 1/4" shorter shaft. As best I could measure, it appeared it would still work. The 5HP Honda at Northern tool was one of the cheapest 5 hp engines they had. It seemed that either engine would bolt right up with the blower, housing, gas tank, etc. I bought the hyd dump system with the understanding the Kawasaki would not run and planned to put the Honda on it. It would have worked, but the only problem was some stuck check valves in the Kawasaki fuel pump.
