Vented Fuel Tank Cap
The fuel system relies on atmospheric pressure to displace fuel as it is pumped to the engine. If the cap's integrated vent is obstructed by debris or a failed check-valve, a vacuum forms within the tank, eventually exceeding the fuel pump's lift capacity and causing the engine to starve and stall. This is a common failure mode where the engine can restart after pressure slowly equalizes through the leak-path.

Carburetor Fuel Shut-off Solenoid
This electromechanical plunger blocks the main fuel jet to prevent backfiring when the engine is turned off. If the internal coil is weakened or the plunger is coated in fuel varnish, it may fail to remain in the retracted position during the high-vibration state of engine operation, effectively cutting off the fuel supply immediately after the initial combustion phase.

Pulse Fuel Pump
The pump utilizes vacuum pulses from the crankcase to move a rubber diaphragm, which draws fuel from the tank to the carburetor. If the diaphragm has developed a micro-tear or if the internal check valves are fouled, the pump may provide enough fuel for a brief startup but fail to maintain the necessary flow rate to sustain continuous engine operation under load.
