Fuel Pump
The pulse-style diaphragm fuel pump relies on crankcase vacuum pulses to move fuel from the rear-mounted tank to the carburetor. Over time, the internal rubber diaphragm can stiffen or develop micro-tears, preventing it from maintaining the necessary flow rate to keep the carburetor float bowl filled during operation. This results in the engine starting on the residual fuel in the bowl and stalling once that small volume is consumed.

Fuel Filter
Accumulated debris or fuel varnish within the filter media increases the fluidic resistance of the fuel line. While the engine is stagnant, fuel may slowly bypass the restriction to fill the carburetor; however, once the engine is under load or high RPM, the demand exceeds the restricted flow rate. This causes a lean-out condition and subsequent engine stall shortly after ignition.

Fuel Tank Cap
The fuel cap contains a specialized one-way vent valve designed to allow atmospheric air to enter the tank as fuel is withdrawn. If this vent becomes occluded by dust or environmental debris, a vacuum forms inside the fuel tank. This negative pressure counteracts the fuel pump's suction, eventually reaching an equilibrium where fuel can no longer be drawn into the fuel lines, starving the engine.
