Several years ago there was a 422 owner that swapped out his 22hp Robin with a 29hp liquid cooled Kawasaki. I remember reading after seven hours on the machine the tran pump went and he just gave up on it. I remember he said it would start right up in zero degree weather and had much more power than the original 22 hp Robin. Anyone remember this thread? Would love to swap out my 22 hp for a 29 hp Kawasaki. What are your thoughts on it?
