Carburetor Assembly (BE94B)
The GCV170 engine on the HRN216 is highly sensitive to ethanol-related deposits in the idle circuit. Surging occurs when the pilot jet is partially blocked, causing a lean condition that triggers the governor to oscillate. Replacing the assembly is the standard resolution as the internal pilot ports are too small for reliable manual cleaning.

Air Cleaner Element
Restricted airflow from a dirty filter causes an incorrect air-fuel ratio. As noted in the search data, the Honda 216 series is sensitive to dust accumulation, and a clogged filter can cause the engine to 'hunt' or surge at low-to-mid RPMs as it struggles to pull air.

Fuel Tank Sump/Line Flush
Water is heavier than gasoline and settles in the bottom of the carburetor float bowl and fuel tank. Even a few drops of water will pass through the main jet intermittently, causing the engine to nearly stall and then surge as the governor snaps the throttle open to compensate.
