The Honda 16166-ZH9-W20 Main Nozzle is a genuine OEM component designed for GX270 horizontal shaft engines. As a direct Honda OEM part, it is manufactured to the exact specification of the original, ensuring the fuel metering your carburetor depends on is restored precisely. This Main Nozzle is confirmed for GX270 engines — verify your engine's serial number against the fitment table to confirm this is the correct version for your unit.
Key Features
- Exact Fuel Metering — as a genuine Honda OEM part, this nozzle is calibrated to the correct orifice size for the GX270 carburetor, delivering the air-fuel ratio the engine was designed to run on.
- Direct OEM Replacement — manufactured to the same specification as the original, this nozzle drops into the carburetor without modification.
- GX270 Fitment — confirmed for GX270 horizontal shaft engines; check your serial number against the fitment table, as Honda supersedes carburetor components at serial breaks.
- Restored Engine Performance — a worn or blocked main nozzle causes lean running, hard starting, and power loss; replacing it with a genuine Honda part brings fuel delivery back to spec.
The main nozzle is the precision metering jet inside the carburetor's main circuit. It controls the volume of fuel drawn into the airstream under load, and its orifice diameter is sized to deliver the correct mixture for the engine's displacement and power output. When the nozzle becomes worn, corroded, or blocked by fuel deposits, the engine runs lean — symptoms include rough running under load, overheating, and loss of power. Replacing it restores the fuel circuit to its original calibration and brings the engine back to its designed operating condition.
