Kohler CV465 15 hp starts and runs fine for several minutes, then dies. let it cool for a few minutes, restarts and runs, then dies. Lapped the valves, new plugs, new coil, new lifters, new gas filter. Still no change. Thoughts?
The next time it happens, immediately spray some carb cleaner into the air horn and see if it will start again. If it starts, but then dies, you have a problem with the fuel system.
