    1. Fuel filter
    2. Safety switches (operator present switch under seat, etc.)
    3. Fuses
    4. Oil level (does Kohler have a low oil safety shutdown?)
    5. Pull air filter and try starting. (you never know)

    Just my .02. Good Luck:confused:

    Also check fuel shut off solenoid for proper operation.

    Check the two fuses on the control panel the one that operates the carb related solenoid may be blown. Happens on mine when I get unit wet.

    Jerry, post up your spec number but I am thinking your engine has the wiring harness with the diodes.

    Sounds like you have power to the starter, fuel shut down solenoid, and SAM in the start position but not the run position. Disconnect the little blue wire from the starter solenoid and do have someone turn the key to run and start and check for power at these devices.

    The fuel shut down solenoid is on the bottom of the carburetor (red wire). The power wire to the SAM is also red, and again the blue solenoid "exciter" wire is light blue.
