  If your Kohler Engine starts but then dies, consider these possibilities: * A restricted fuel tank cap vent may be the cause. Unclog the fuel tank cap vent. * Poor fuel, or contaminants in the fuel system, can lead to this issue. Replace the fuel and clean the fuel system. * The choke or throttle controls may be faulty or misadjusted. Adjust or replace them as needed. * Loose wires or connections might be shorting the ignition module. Secure any loose wires and connections. * A faulty cylinder head gasket could be the problem; replace it. * A faulty carburetor may need replacing or repair. * An intake system leak should be repaired.
