The Honda 16166-Z9M-811 Main Nozzle is a genuine OEM component designed for GCV170 and GCV200 vertical shaft engines and the HRX217 lawn mower. As a direct Honda OEM part, it is manufactured to the same specification as the original, ensuring correct fuel metering without adjustment or modification. This nozzle is the right call when rebuilding a carburetor on any of these units, and verifying the part number 16166-Z9M-811 against your machine's serial number before ordering is always a smart step, as Honda does supersede parts at production breaks.
Key Features
- Accurate Fuel Metering — as a genuine Honda OEM part, this nozzle is calibrated to the exact orifice dimensions the carburetor requires, delivering the correct air-fuel ratio for clean starting and smooth throttle response
- Direct Carburetor Fit — built to original dimensions for drop-in installation during a carburetor rebuild or overhaul on GCV170 and GCV200 engines and the HRX217 mower
- Broad Fitment Coverage — suits GCV170 and GCV200 vertical shaft engines as well as the HRX217 lawn mower, making it a practical stocking part for shops servicing this equipment family
- Serial Number Verification Recommended — Honda updates parts at specific production breaks, so confirm your machine's serial number against the fitment table to ensure this is the correct nozzle for your unit
The main nozzle is a precision metering component inside the carburetor. It controls the volume of fuel drawn into the airstream under mid-range and full-throttle conditions, and its calibrated bore is what keeps the air-fuel mixture within the range the engine needs to run efficiently. When the nozzle is worn, partially blocked, or damaged, the engine typically responds with rough running, hesitation under load, or an overly rich or lean condition that no amount of idle-mixture adjustment can fully correct. Replacing it with a correctly sized OEM part restores the carburetor's ability to meter fuel as Honda intended.
