I don't have a Kawasaki at the moment, but when it came down to keeping a tractor with a Briggs V twin or a Kohler 7400 V twin, I did not want to have the constant carb issues with Briggs, so I kept the tractor with the Kohler or, "Rehlco" engine. But there's a reason Kawasaki's are on a lot of commercial mowers. Maybe in the future, I will do a Kawasaki swap.
