What I think is funny is that the Cub has a rather large hump under the seat area for a shaft that is only an inch or so in diameter (probably designed by the marketing department). On the engine - both will likely outlive the chassis (as long as you change oil once or twice a season). Although the Kohler does have a nasty habit of sometimes giving off an extra pop when turning it off - it doesn't seem to be a major issue (other folks on this forum have seen this too). BTW - The best engines out there tend to be the Honda red top engines (the blue are their consumer line). The red ones are top notch but you pay dearly for the quality.
In any case - good luck with your purchase - both will likely do what you need.
