Carburetor Assembly
The pilot and main jets in this model have extremely small apertures that easily become restricted by fuel varnish or debris. This restriction creates a lean air-fuel mixture that lacks the energy density to maintain the target RPM under load, forcing the electronic governor to perpetually over-correct, resulting in the surging/hunting cycle.

Throttle Control Motor (Stepper Motor)
This motor translates electrical signals from the inverter into mechanical movement of the throttle plate. Internal gear stripping or carbon-induced friction on the throttle shaft causes a 'lag' in response time; the resulting hysteresis prevents the ECU from achieving the precise throttle position required for the load, causing the RPM to oscillate.

Spark Plug
Under load, combustion chamber pressures increase, requiring higher voltage to bridge the spark gap. A fouled or improperly gapped plug may experience intermittent misfires that are not present at idle, sending erratic RPM data to the control module and inducing a hunting behavior as the system tries to stabilize engine speed.
