The Honda 16166-ZDJ-821 Main Nozzle is a genuine OEM part designed for GXR120 horizontal shaft engines. As a direct Honda OEM component, this nozzle is manufactured to the exact specifications required for correct fuel metering in the GXR120 carburetor. Confirm your engine's serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks and this ensures you receive the right nozzle for your unit.
Key Features
- Correct Fuel Metering — as a genuine OEM Main Nozzle, this part is dimensioned to Honda's exact orifice specification, ensuring the carburetor delivers the proper air-fuel mixture across the GXR120's operating range
- Direct OEM Replacement — sourced from Honda, part number 16166-ZDJ-821 drops into the GXR120 carburetor without modification, restoring the fuel circuit to its original operating condition
- GXR120 Fitment — built specifically for the GXR120 horizontal shaft engine; verify your serial number against the fitment table to confirm this is the correct supersession for your engine's build
The main nozzle is the precision-calibrated metering jet inside the carburetor responsible for delivering the correct volume of fuel into the air stream at mid-range and full throttle. Its orifice diameter is tuned to the engine's displacement and air flow, so even slight wear, varnish buildup, or damage to the nozzle upsets the fuel ratio and causes hard starting, rough running, or power loss under load. Replacing a worn or fouled main nozzle with the correct OEM part restores crisp throttle response and consistent power output to the GXR120 engine.
