Vacuum Fuel Pump
The fuel pump on this model operates via vacuum pulses from the crankcase. If the internal diaphragm becomes brittle or develops a micro-perforation, it cannot maintain the volumetric flow rate required to replenish the carburetor bowl, causing the engine to stall once the bowl's static level is depleted.

Carburetor Overhaul Kit
The main jet and nozzle are susceptible to varnish and debris accumulation. When the engine transitions from the starting/idle circuit to the main circuit, an obstruction prevents the necessary air-fuel ratio, resulting in an immediate lean-condition stall.

Fuel Tank Cap
Small engines require a vented fuel system to prevent vacuum lock. If the cap's integrated check valve fails or becomes clogged, the resulting negative pressure inside the tank overcomes the fuel pump's suction capacity, starving the engine of fuel shortly after startup.
