The Honda 16166-Z4V-WB1 Main Nozzle is a genuine OEM component designed for GX200 horizontal shaft engines. As the factory-sourced replacement, this nozzle is made to the exact specification Honda engineers set for the GX200 carburetor, ensuring correct fuel delivery right out of the box. Verify part number 16166-Z4V-WB1 against your engine's serial number and parts diagram before ordering to confirm this is the correct variant for your unit.
Key Features
- Genuine OEM Fuel Metering Accuracy — sourced directly from Honda, this nozzle is sized and calibrated to deliver the precise fuel-to-air ratio the GX200 carburetor was designed around, avoiding the rich or lean running conditions an incorrect or worn nozzle causes.
- Direct Carburetor Replacement — an exact-fit drop-in for the GX200 carburetor assembly, this part installs without rework or adaptation and restores the fuel circuit to its original operating condition.
- Built for GX200 Horizontal Shaft Engines — confirmed fitment for GX200 engines; always cross-reference your engine's serial number against the fitment table to ensure this nozzle applies to your specific production run.
The main nozzle is a small but critical metering component inside the carburetor. It governs how much fuel is drawn into the airstream under mid-range and full-throttle conditions, directly influencing power output, fuel efficiency, and throttle response. When the main nozzle becomes clogged, eroded, or damaged, the engine will run lean, surge, lose power under load, or fail to reach full operating speed — symptoms that are often misdiagnosed as carburetor or ignition faults. Replacing a worn or fouled nozzle with the correct Honda OEM part restores clean, consistent fuel delivery across the GX200's full operating range.
