The Honda 16166-ZF1-005 Main Nozzle is a genuine OEM replacement 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 component it replaces, ensuring a proper fit in the carburetor assembly of these machines. Honda supersedes parts at serial-number breaks, so verify your snow blower's serial number against the fitment table before ordering to confirm part number 16166-ZF1-005 is correct for your unit.
Key Features
- Genuine OEM Fuel Metering — manufactured by Honda to the exact jet diameter and flow calibration the original carburetor requires, maintaining the correct air-fuel ratio for cold-weather starting and full-load clearing performance.
- Direct Carburetor Fit — this nozzle installs into the carburetor body without modification, restoring the original fuel circuit geometry that Honda engineered for the HS522, HS622, and HS624.
- Two-Stage Snow Blower Fitment — designed specifically for the HS522, HS622, and HS624 two-stage snow blowers; confirm your serial number against the fitment table before purchasing.
- Worn Nozzle Consequences — a degraded or clogged main nozzle causes rough running, hard starting in cold conditions, and loss of clearing power; replacing it restores clean fuel delivery and consistent engine response.
The main nozzle is a precision-drilled jet located inside the carburetor body. It meters the correct volume of fuel into the airstream at mid to full throttle, allowing the engine to develop the power needed to drive the augers and blower of a two-stage snow blower through heavy, wet snow. Because the orifice is very small, partial blockages from stale fuel or varnish deposits can severely disrupt the air-fuel mixture, causing stumbling, surging, or an inability to run under load. Replacing a worn or obstructed main nozzle with a genuine Honda part restores the precise fuel calibration the carburetor was designed to deliver.
