The Honda 16166-ZL8-H01 Main Nozzle is a genuine OEM replacement designed for HS520 and HS720 single-stage snow blowers. Sourced directly from Honda, this part carries the same specifications as the original component it replaces, ensuring a proper fit in the carburetor assembly. Honda supersedes parts across serial ranges, so confirm your unit's serial number against the fitment table before ordering.
Key Features
- Genuine OEM Fuel Metering — manufactured to Honda's original calibration, this nozzle delivers the correct fuel-to-air ratio the carburetor is tuned to, keeping combustion efficient and consistent in cold-weather operation.
- Direct OEM Replacement — engineered to the same dimensions as the factory original, this part installs into the carburetor without modification on compatible HS520 and HS720 snow blowers.
- Fits HS520 and HS720 Single-Stage Snow Blowers — verify your serial number against the fitment table, as Honda updates part numbers at serial breaks and the correct nozzle depends on your specific production range.
- Restores Carburetor Performance — a worn or clogged main nozzle disrupts fuel delivery, causing hard starting, rough running, or loss of power. Replacing it with this OEM part restores clean fuel flow and dependable engine output.
The main nozzle is a precision-drilled fuel metering component seated inside the carburetor body. It controls the volume of fuel drawn into the airstream during mid-range and full-throttle operation, making it central to how the engine responds under load. When the nozzle becomes clogged with varnish deposits or worn beyond its original diameter, fuel delivery becomes erratic — symptoms typically include rough running, hesitation, or an engine that starts but will not hold speed under the demands of clearing snow.
