The Honda 16166-Z2B-003 Main Nozzle is a genuine OEM component designed for the HRC216 lawn mower. Sourced directly from Honda, this part meets the exact specifications of the original installed at the factory, ensuring correct fuel delivery through the carburetor. If your HRC216 is running rough, surging, or struggling to maintain consistent speed under load, a worn or clogged main nozzle is a common culprit — and this is the correct OEM replacement to restore proper operation.
Key Features
- Genuine OEM Fuel Metering Accuracy — manufactured to Honda's exact orifice dimensions, ensuring the correct air-fuel mixture is delivered at all throttle positions for clean, consistent combustion
- Direct Carburetor Replacement — this is the OEM-specified main nozzle for the HRC216, designed to drop into the carburetor without modification or adaptation
- Fitment for the HRC216 Lawn Mower — confirm your serial number against the fitment table, as Honda supersedes carburetor components at production breaks and the correct nozzle can vary by build range
- Restores Engine Response — a degraded or blocked main nozzle causes surging, lean-running, and loss of power under load; replacing it with this genuine part brings throttle response back to spec
The main nozzle is a precision-metered jet inside the carburetor that controls how much fuel enters the airstream during normal running operation. Fuel is drawn through the nozzle's calibrated opening and mixed with incoming air before entering the combustion chamber — so even a minor restriction or wear-related enlargement of the orifice throws off the air-fuel ratio. When the main nozzle fails or becomes blocked, the engine typically runs lean, surges at mid to full throttle, or hesitates under load. Replacing it restores the precise metering the carburetor was designed around and returns the HRC216 to its normal operating performance.
