The Honda 16166-Z1A-H02 Main Nozzle is a genuine OEM component designed for HS520 and HS720 single-stage snow blowers. As a factory-original part, this nozzle is built to Honda's exact dimensions to restore correct fuel metering through the carburetor. Confirm your snow blower's serial number against the fitment table before ordering, as Honda supersedes parts at production breaks and serial ranges determine which nozzle applies to your unit.
Key Features
- Precise Fuel Metering — as a genuine OEM nozzle, this part is dimensioned to Honda's exact orifice specification, ensuring the carburetor delivers the correct air-fuel mixture at full throttle
- Direct OEM Replacement — this nozzle drops into the carburetor of HS520 and HS720 single-stage snow blowers with no adaptation, restoring the original fuel circuit
- Serial Number Matters — Honda issues part supersessions at production serial breaks; verify your unit's serial number against the compatibility table to confirm part number 16166-Z1A-H02 is correct for your machine
- Restores Full-Load Performance — a worn or clogged main nozzle causes rich or lean conditions under load; replacing it brings the engine back to its correct power output when clearing snow
The main nozzle is the primary fuel-metering jet inside the carburetor, responsible for delivering the correct volume of fuel into the airstream when the engine is running under load. On a single-stage snow blower like the HS520 and HS720, where the engine works hard driving the rubber paddle auger through packed snow, consistent fuel delivery at the main circuit is essential for steady power. When the main nozzle becomes clogged, worn, or damaged, the engine will run lean under load, surge, lose power, or shut down entirely — all of which reduce the machine's ability to clear snow effectively.
