Carburetor Assembly
The surging behavior is a mechanical manifestation of a 'lean hunt.' Internal orifices and jets within the carburetor have likely become constricted by fuel varnish or ethanol-related debris, restricting fuel flow. This forces the electronic stepper motor to constantly adjust the throttle plate to prevent a stall, creating the rhythmic surging until the mixture becomes too lean to support combustion.

Fuel Filter
A partially restricted fuel filter limits the volume of fuel available to the carburetor's float bowl. Under load or during startup sequences, the engine consumes fuel faster than the filter allows it to be replenished, causing the fuel level in the bowl to drop and the engine to surge as it starves before eventually shutting down.

Spark Plug
While primarily a fuel issue, a fouled or improperly gapped spark plug can cause incomplete combustion cycles that mimic surging. If the electrode has significant carbon buildup from previous lean-run conditions, the inconsistent ignition timing will prevent the engine from stabilizing at its programmed idle or run speed.
