Well we have two and both are acting up alike. One cylinder drops out and goes back to running. I can not believe they are still in business. You can not reach anyone there to talk to. They direct you to a parts warehouse that doen't have a clue. 3 years of battling F'n Kohler motors instaed of making money with them. Now I hear they have a fix by changing the wire harness. I changed a coil to no effect. We will not buy another piece of equipment with a kohler motor on it. I feel better now.
