I have worked with a lot of air cooled engines and there was a time in the past where a Kohler would deliver a decent amount of hoursepower for about twice as long as a Briggs, literally 3000 hours versus 1500 for a Briggs.
However times are a changing and in my opinion Kohler has lost that edge due to improvements made by Briggs primarily in their Intek line of engines.
For a number of years Briggs lagged even Generac in quality, way back Generac went with pressurized lubrication for the mains while Briggs added an oil pump which only circulated oil through the filter sticking with a slinger to distribute oil around the crankcase, stupid stuff but they where stuck in an engineering rut which they finally got out of.
Then theres Hondas
While interesting information, it doesn't help answer the question of Kawasaki vs Briggs... specifically Kawasaki FR series vs Briggs Endurance series.
