Carburetor Assembly
The most common failure mode is a partial blockage in the main jet or emulsifier tube. When the governor opens the throttle to compensate for the mechanical load of the blades, the restricted fuel flow results in an air-fuel ratio that is too lean to support combustion under high cylinder pressure. Replacing the assembly ensures all internal micro-passageways are clear of ethanol-induced corrosion.

Fuel Pump
These engines use a vacuum-pulse diaphragm pump that relies on crankcase pressure fluctuations. If the internal diaphragm has developed micro-perforations or lost its elasticity, its volumetric efficiency drops. While it may provide enough fuel to maintain idle or low-RPM operation, it cannot provide the flow rate required to keep the carburetor bowl filled during high-load events.

Resistor Spark Plug Set
Under heavy mechanical load, the effective compression pressure within the combustion chamber increases significantly. This higher pressure increases the electrical resistance across the spark plug gap; if the plugs are fouled or the gap has widened due to electrode erosion, the ignition coil may not be able to bridge the gap, leading to a load-induced misfire and subsequent stall.
