Carburetor Assembly
The surging is caused by a lean-burn condition where the air-fuel ratio is incorrect due to microscopic obstructions in the carburetor's internal galleries. This triggers the stepper motor governor to oscillate the throttle plate in a feedback loop to maintain RPM. Because the internal orifices on inverter generators are too small for reliable manual cleaning, a full replacement of the carburetor assembly is the standard engineering resolution to restore factory flow rates.

Spark Arrester Screen
Over time, carbon particulates accumulate on the fine mesh of the spark arrester within the muffler, creating excessive exhaust backpressure. This prevents the engine from effectively scavenging spent gases during the exhaust stroke, which leads to poor volumetric efficiency and an erratic idle that mimics fuel-related surging before the engine eventually chokes out.

Fuel Tank Cap Assembly
A failure in the fuel cap's atmospheric vent prevents air from entering the tank as fuel is drawn out. This creates a negative pressure (vacuum lock) inside the tank that eventually overcomes the gravity or pump pressure feeding the carburetor. As the fuel level in the float bowl drops, the engine runs lean and surges before eventually stalling due to total fuel starvation.
