Small Engines (Lawn Mowers, etc.): kohler 16.5, kohler command, fuel valve

Question
mod#cv16s spec#43513  serial#2807502103 My kohler command 16.5 starts and runs great for about 10-15 minutes then acts like it runs out of gas. You can choke it and it will run a little longer then it dies alltogether. It wiil start again after it sits for about 1/2 an hour. The fuel filter has gas in it when it dies and it flows through fine. Any suggestions?

Check for stuck float, plugged fuel filter or fuel line. All tanks have a screen inside them to catch larger particles, and some also have a inline fuel filter. If everything checks ok, the passages inside the carb are plugged, Surging, only runs on choke, sputtering: Is the air filter dirty? With the bowl as the lowest part of the fuel system, any dirt or water will wind up here. Turn off the fuel valve, or drain the gas tank, then place a rag under the bowl to catch the gas that will run out. Loosen the "nut" that holds the bowl on, and after the gas has stopped draining remove the nut and bowl, but do not let the float swing all the way down! Wipe out the bowl. The "nut" usually contains 1 or 2 very small passages, soak in (or spray with) carb cleaner and use a wire bread-tie or other soft wire to poke out the holes. Blow out with compressed air, if available. Put the bowl back on and try to start it. If it still will not start, it needs a good soaking and a rebuild kit
