I've never messed with Kohler engines, only their generators, and they are complete crap. I used to fight with the 'authorized dealer" of the week on getting warranty work done for my customers. They are hte most popular marine gas generators out there, because they are the cheapest. I met the Kohler reps while I was at service classes for Carver Yachts, I gave them both barrels. Three days later, I had the same people at service classes for Cruisers Yachts, I just sat in the back and laughed out loud every time they mentioned warranty(yea, I had a few in me at the time), they knew better to say something to me in front of another group of people. I told them the most cost efficient way to fix a Kohler generator was to replace it with a Westerbeke
