The Honda 16166-Z1T-A12 Main Nozzle is a genuine OEM component designed for the FC600 tiller. As a direct Honda OEM part, it is manufactured to the exact specifications of the original, ensuring the carburetor meters fuel correctly and the tiller runs as it should. Confirm your serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks.
Key Features
- Correct Fuel Metering — as a genuine OEM Main Nozzle, this part delivers the exact orifice sizing Honda specifies, keeping the carburetor's fuel-to-air ratio on target across the throttle range.
- Direct OEM Replacement — sourced from Honda, this nozzle matches the original part number 16166-Z1T-A12 and drops into the FC600 carburetor without modification.
- FC600 Tiller Fitment — confirmed for the Honda FC600 tiller; verify your unit's serial number against the fitment table to ensure this is the correct nozzle for your serial range.
- Engine Response Restored — a worn or clogged main nozzle causes rich or lean running, rough throttle response, and hard starting; replacing it with a fresh OEM nozzle brings fuel delivery back to spec.
The main nozzle is a small-diameter metering jet seated inside the carburetor body. It controls how much fuel is drawn into the airstream under mid-to-full throttle operation, making it central to clean combustion and consistent power output. When the nozzle becomes worn, corroded, or varnished from stale fuel, the tiller may run rough, surge, lose power, or refuse to start — a new OEM nozzle restores the precise fuel flow the engine depends on.
