Fuel Shut-off Solenoid
This electromechanical plunger sits at the base of the carburetor bowl to prevent backfiring by closing the fuel jet when the engine is off. If the solenoid's internal electromagnetic coil fails or the plunger becomes stuck due to fuel lacquer, it will fail to stay open when the ignition key returns to the 'Run' position, starving the engine of fuel immediately after startup.

Pulse Fuel Pump
The engine utilizes a vacuum-driven diaphragm pump to move fuel from the tank to the carburetor. If the internal diaphragm is perforated or the vacuum pulse line from the crankcase is cracked, the pump cannot maintain the flow rate required to sustain combustion once the initial fuel in the carburetor bowl is consumed.

Operator Presence (Seat) Switch
The safety interlock system is designed to ground the ignition coil if it detects the operator is not in the seat while the parking brake is off or the blades are engaged. A high-resistance fault in this switch or a loose mechanical connection can cause intermittent grounding of the magneto, leading to the engine dying immediately after the vibration of the engine start occurs.
