The Honda 16166-ZG0-811 Main Nozzle is a genuine OEM replacement designed for EG650 generators, G100 horizontal shaft engines, and WB15 water pumps. As a factory-original component, this nozzle is manufactured to Honda's exact specifications, ensuring correct fuel metering and consistent air-fuel mixture delivery. Confirm your unit's serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks and more than one variant may be listed for these models.
Key Features
- Correct Fuel Metering — as a genuine OEM part, this nozzle is calibrated to Honda's exact orifice sizing, ensuring the carburetor delivers the right air-fuel ratio under load
- Direct OEM Replacement — manufactured by Honda, this component installs directly in place of the original without adaptation, preserving factory carburetor performance
- Broad Fitment — covers EG650 generators, G100 horizontal shaft engines, and WB15 water pumps; verify your serial number against the fitment table to confirm the correct variant for your unit
- Restores Clean Running — a worn or clogged main nozzle causes lean running, rough idle, power loss, and hard starting; replacing it with this OEM part brings fuel delivery back to spec
The main nozzle is a precision-calibrated fuel-metering component seated inside the carburetor body. It controls the volume of fuel drawn into the airstream at mid-range and full throttle, and its orifice diameter is matched exactly to the engine's displacement and tuning. When the nozzle becomes clogged with varnish or debris, or erodes over time, the engine runs lean, loses power, hesitates under load, or refuses to start cleanly. Replacing it with the correct OEM nozzle restores accurate fuel delivery and smooth operation across the full throttle range.
