The Honda 16166-Z8P-801 Main Nozzle is a genuine OEM component designed for GXV630, GXV660, and GXV690 vertical shaft engines. As a direct Honda OEM part, it is manufactured to the exact specification of the original, ensuring the carburetor meters fuel at the correct rate for these engines. This nozzle is compatible across the GXV630, GXV660, and GXV690 engine series — confirm your engine's serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks.
Key Features
- Correct Fuel Metering — as a genuine OEM part, this nozzle is sized to Honda's original specification, delivering the precise fuel flow the carburetor on these engines is calibrated for
- Direct OEM Replacement — part number 16166-Z8P-801 installs directly in place of the original, with no reworking of the carburetor body required
- Broad GXV-Series Coverage — fits GXV630, GXV660, and GXV690 vertical shaft engines, making it a practical stock item for shops servicing this engine family
- Check Your Serial Number — Honda updates parts at production serial breaks, so cross-reference your engine's serial number with the fitment table to confirm this is the correct nozzle for your unit
The main nozzle is the primary fuel-delivery point inside the carburetor. It draws fuel from the float bowl and discharges it into the venturi airstream, where it atomizes and mixes with incoming air before entering the combustion chamber. The nozzle's bore diameter is calibrated to match the engine's displacement and airflow, so a worn, clogged, or incorrectly sized nozzle will disrupt the air-fuel ratio — leading to hard starting, rough running, poor throttle response, or excessive fuel consumption on the GXV630, GXV660, and GXV690 engines this part is built for.
