The Honda 16166-Z0Y-003 Main Carburetor Nozzle is a genuine OEM component designed for GCV190 and GSV190 vertical shaft engines, as well as HRB217 and HRX217 lawn mowers. As a direct Honda OEM part, it is manufactured to the same specification as the nozzle originally installed at the factory, ensuring correct fuel metering geometry right out of the box. Confirm your unit's serial number against the fitment table before ordering, as Honda supersedes carburetor internals at production breaks and more than one nozzle variant may be listed for these models.
Key Features
- Correct Fuel Metering — as a genuine OEM nozzle, the orifice diameter and fuel delivery profile match Honda's original specification, maintaining the air-fuel ratio the carburetor was calibrated to deliver
- Direct OEM Replacement — this part drops into the carburetor bore without modification, restoring the fuel circuit to its original condition
- Broad Fitment — covers GCV190 and GSV190 vertical shaft engines and HRB217 and HRX217 lawn mowers; check your serial number against the fitment table to confirm the correct nozzle for your unit
- Restored Engine Response — a worn or damaged main nozzle causes lean running, hesitation under load, and hard starting; replacing it returns crisp throttle response and stable operation
The main carburetor nozzle is the precision metering point at the heart of the carburetor's main fuel circuit. It controls the volume of fuel drawn into the airstream at mid to full throttle, and its calibrated orifice is what keeps combustion consistent across the engine's power range. When this nozzle wears, erodes, or becomes partially blocked, the engine is starved of the correct fuel charge — producing symptoms such as rough running, loss of power, and difficulty sustaining load. Replacing it with a genuine Honda part restores the fuel delivery the carburetor was designed to produce.
