Carburetor Assembly
The most common cause for stalling under mechanical load is a restricted main jet or internal varnish. When the engine governor opens the butterfly valve to compensate for load, the fuel circuit fails to provide the required volume, resulting in a lean-condition stall. Replacing the assembly ensures all internal transition ports are clear.

Voltage Regulator / Rectifier
If the stall occurs specifically when the PTO is engaged, the regulator is likely failing to convert AC stator output to DC effectively. The high amperage draw of the electric clutch collapses the electrical bus, starving the ignition coils or the fuel solenoid of the voltage necessary to function.

Fuel Pump
The vacuum-pulse fuel pump may fail to provide sufficient flow rate at high RPMs or high load. If the diaphragm is degraded, it cannot overcome the head pressure required to keep the carburetor bowl full during sustained high-demand operation, leading to fuel starvation.
