The Honda 16166-Z8B-841 Main Nozzle is a genuine OEM component designed for GCV160 and GCV190 vertical shaft engines. As a direct Honda OEM part, it is manufactured to the same specification as the original, ensuring proper fuel metering and consistent carburetor performance. This main nozzle is the correct replacement for both the GCV160 and GCV190 engine series — verify your engine's serial number against the fitment table to confirm the right application for your unit.
Key Features
- Correct Fuel Metering — as a genuine Honda OEM part, this nozzle is dimensioned to deliver the precise fuel flow the carburetor requires for clean starting and smooth running at all throttle positions.
- Direct OEM Replacement — sourced directly from Honda, this nozzle installs into the carburetor without alteration, restoring original fuel circuit performance.
- Fits GCV160 and GCV190 Engines — designed specifically for Honda's residential vertical shaft engine series; check your serial number against the fitment table before ordering.
- Restores Engine Response — a worn or clogged main nozzle causes lean running, hesitation under load, and hard starting; replacing it brings fuel delivery back to spec.
The main nozzle is the precision metering point inside the carburetor that controls how much fuel enters the airstream during mid-range and full-throttle operation. Fuel is drawn through the nozzle by intake vacuum, and the nozzle's bore diameter determines the fuel-to-air ratio the engine runs on. When the nozzle becomes clogged with varnish deposits or worn beyond its original dimensions, the engine runs lean, loses power under load, hesitates on acceleration, or refuses to start — replacing this component is a fundamental step in any carburetor service or rebuild.
