Be careful with Kohlers....most are made in China now and are real POS's....not sure which if any models are still made in Wisconsin. I was so ticked off a few years ago when I purchased a Husq mower, with a Kohler engine (I purposely choose the Kohler over the Honda) and when I got home, it said "Made In China" on it.
So far, only some bits and pieces of my carb have corroded (mostly the vacuum needle) and so I threw a genuine Keihen carb I had laying around on it....fabbed up some linkage, and she runs fine.
But oh my.....I about flew my stack after the 4th time I moved, I went to change the oil, and it said "Made in China" on it. I was close to coming unglued. LOL!!
