    Hi Guys, I'm looking for some advice on a problem with a 9 year old Kohler CV16S.

    It runs fine for maybe a half hour, then eventually cuts out. I've replaced the carburetor & solenoid, checked all the wiring & connections, replaced the fuel filter and fuel hose upstream from the filter.

    When it dies, I can see that there's no fuel in the filter housing. If I wait, it will eventually fill to about half full and I can run it again for a while.

    The port from the fuel tank is clear, but it just won't continue to draw fuel at a reasonable rate. When it does run, it barely draws enough fuel to show anything in the filter housing.

    Any ideas?

    thanks, Jack

    That title should have said "Fuel" starved...

    Sounds a case of vapor lock(gas cap clog?) even perhaps dirty gas tank and or screen inside tank.

    A blocked vent hole in the gas cap could cause your symptoms. Try loosening the cap for a few seconds and see what happens.

    There is no screen in the gas tank, it flows directly into the fuel line. The problem persists when I remove the gas cap, and it's a new cap, too.

    Am I wrong? I think these have a mechanical fuel pump.

    It did it again yesterday, going up a slight incline. I had replaced the Kohler fuel filter with a generic one with a larger housing. Could it be something as simple as having too much airspace in the filter housing?
