The Honda 16166-ZK8-V01 Main Nozzle is a genuine OEM component designed for GX160 horizontal shaft engines. As a direct Honda OEM part, it is manufactured to the exact dimensions and tolerances required for correct fuel metering in the carburetor. Confirm your engine's serial number against the fitment table before ordering to ensure this nozzle corresponds to your production range.
Key Features
- Exact Fuel Metering — as a genuine Honda OEM part, this nozzle is dimensioned to the precise orifice specification the GX160 carburetor requires, ensuring the correct air-fuel ratio under load.
- Direct OEM Replacement — manufactured by Honda to replace the original nozzle without modification, restoring the carburetor to its intended operating condition.
- GX160 Fitment — sourced specifically for GX160 horizontal shaft engines; verify your serial number against the compatibility table to confirm the correct variant for your unit.
- Fuel Efficiency and Power — a worn or blocked main nozzle disrupts the fuel circuit, causing rich or lean running, poor throttle response, and loss of power; this replacement restores clean, consistent delivery.
The main nozzle is the precision-metered passage inside the carburetor through which fuel is drawn into the airstream during mid-range and wide-open throttle operation. Its orifice diameter is calibrated to deliver the correct volume of fuel relative to airflow, maintaining a stable air-fuel mixture across the engine's operating range. When the nozzle is blocked by varnish deposits or worn beyond its original dimension, the engine may surge, run lean under load, or fail to reach full power — making replacement of this small but critical component essential to restoring normal operation.
