I just bought a Kawasaki 11.5 hp with electric start for $550 online, it appears to be a great engine that has an oil filter, larger oil capacity, and a much larger muffler than the honda. It mates to 5.5 gpm 2300 psi belt drive for fleet washing/house washing. The honda you are talking about is probably the most dependable engine ever built thats why it was copied by a lot of chinese companies and Kohler looks to have a copy of it as well. I just took a chance on the Kawi I just bought. I'll never buy another Honda clone again although I did get almost 3 solid years out of one before it sucked in a valve, they (clones) are terribly cheaply built.
