Customer Question

I have a Craftsman 26 HP tractor. Kohler Courage plus engine model SV 735. It runs fine until I add fuel. Then it runs rough w/ black smoke. Eventually it'll settle and run fine until I add fuel again.

This only happens when you add fuel to the tank? My other thought is that if you are saying add fuel, meaning increase the throttle. It sounds to me like the carburetor is leaking a little bit so that it is flooded or the choke is out of adjustment or stuck so that it is causing the engine to smoke.
