The Honda 16166-ZK8-H81 Main Nozzle is a genuine OEM component designed for HS522, HS622, and HS624 two-stage snow blowers. As a direct Honda OEM part, it is manufactured to the same specifications as the original, ensuring an exact fit with no guesswork. This nozzle is built for HS522, HS622, and HS624 models — confirm your unit's serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks and the correct nozzle can vary by production run.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this part meets the same specifications as the nozzle your snow blower left the factory with, ensuring correct fuel metering at the main jet circuit.
- Direct Replacement — engineered to drop into the carburetor of HS522, HS622, and HS624 two-stage snow blowers without alteration.
- Serial Number Matters — Honda updates parts at production breaks, so cross-check your snow blower's serial number against the fitment table to confirm part number 16166-ZK8-H81 is the right nozzle for your unit.
- Restore Proper Fuel Delivery — a worn or clogged main nozzle causes rich or lean running, hard starting, and loss of power under load; replacing it restores clean, consistent engine performance.
The main nozzle is a precision-drilled fuel metering component inside the carburetor. It controls the volume of fuel drawn into the airstream at mid to full throttle, and the calibrated orifice size is matched to the engine's air flow and displacement. When the nozzle becomes clogged with varnish from stale fuel, or when the orifice wears, the engine receives an incorrect fuel mixture — resulting in rough running, power loss, or difficulty starting in cold weather. Replacing a damaged or blocked main nozzle with a genuine Honda part restores the carburetor's ability to deliver the correct mixture across the operating range of the snow blower.
