The Honda 16166-Z8B-911 Main Nozzle is a genuine OEM carburetor component designed for GCV160 and GCV190 vertical shaft engines and the HRS216 lawn mower. As a direct Honda OEM part, it matches the original metering specifications exactly, ensuring the carburetor delivers the correct air-fuel ratio for consistent starting and smooth power delivery. Confirm your unit's serial number against the fitment table before ordering, as Honda supersedes parts at production breaks and this nozzle is application-specific.
Key Features
- Correct Fuel Metering — an OEM main nozzle holds the exact orifice diameter Honda engineered for these carburetors, keeping the air-fuel mixture within spec across the RPM range
- Direct OEM Replacement — this part installs into the carburetor body of GCV160 and GCV190 engines and the HRS216 mower with no modification, restoring the original fuel delivery path
- Broad GCV-Series and Mower Coverage — fits GCV160 and GCV190 vertical shaft engines as well as the HRS216 lawn mower, including models across multiple serial ranges
- Serial Number Verification Recommended — Honda updates carburetor components at production serial breaks; check your machine's serial number against the fitment table to confirm this nozzle is correct for your unit
The main nozzle is a precision metering jet inside the carburetor that controls how much fuel enters the airstream during mid-range and full-throttle operation. Its orifice size is calibrated to the specific carburetor design, so a worn, blocked, or incorrect nozzle causes lean running, hesitation under load, or an engine that surges and refuses to hold steady speed. Replacing a degraded nozzle with a genuine Honda part restores the fuel delivery the carburetor was designed around, bringing combustion back into the range where the engine runs cleanly and pulls its rated output.
