The Honda 16166-Z8S-901 Main Nozzle is a genuine OEM component designed for FRC800 tillers and GX240 horizontal shaft engines. Sourced directly from Honda, this part meets the same specifications as the nozzle installed at the factory, ensuring correct fuel delivery through the carburetor. Confirm your machine's serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks and fitment can vary within a model line.
Key Features
- Accurate Fuel Metering — as a genuine OEM part, this main nozzle is manufactured to Honda's exact orifice dimensions, ensuring the carburetor delivers the correct air-fuel mixture across the engine's operating range.
- Direct OEM Replacement — part number 16166-Z8S-901 replaces the original nozzle without modification, dropping into the carburetor body as the factory unit did.
- Broad Fitment — fits FRC800 tillers and GX240 horizontal shaft engines; verify your serial number against the fitment table to confirm this is the correct nozzle for your unit.
- Restored Engine Response — a worn or clogged main nozzle starves the engine of fuel under load, causing rough running, bogging, and hard starting; replacing it restores clean throttle response and steady power output.
The main nozzle is a precision-calibrated jet inside the carburetor that meters the volume of fuel drawn into the airstream during normal running. Its orifice size is calculated to match the engine's displacement and air flow, so the combustion mixture stays within the correct ratio across throttle positions. When the nozzle becomes worn, corroded, or partially blocked by varnish deposits, the engine loses the ability to maintain a consistent mixture, resulting in power loss, rough idling, and increased fuel consumption.
