The Honda 16166-ZE3-W10 Main Nozzle is a genuine OEM replacement designed for GX340 horizontal shaft engines. As a direct Honda OEM component, this part is manufactured to the same specifications as the original, ensuring correct fuel metering geometry without adaptation. Confirm your engine's serial number against the fitment table before ordering, as Honda supersedes carburetor components at serial breaks within the GX340 line.
Key Features
- Correct Fuel Metering — as a genuine OEM main nozzle, the orifice diameter and flow characteristics match Honda's original specification, so the carburetor delivers the air-fuel ratio the GX340 engine is tuned for
- OEM Direct Replacement — sourced directly from Honda, this part installs in place of the original with no modification, maintaining the carburetor's calibration right out of the box
- GX340 Fitment — built specifically for GX340 horizontal shaft engines; verify your serial number against the compatibility table to confirm this is the correct nozzle for your unit
- Restored Engine Performance — a worn or clogged main nozzle disrupts fuel delivery at mid to full throttle, causing rough running, hesitation, or rich/lean conditions; replacing it brings fuel flow back to spec
The main nozzle is a precision-calibrated component inside the carburetor's main circuit. It meters the volume of fuel drawn into the airstream under normal running and load conditions, and its bore diameter is what sets the engine's fuel mixture at mid to full throttle. When the nozzle becomes worn, corroded, or partially blocked by deposits, the GX340 engine will run unevenly, lose power under load, or struggle to hold a steady speed. Replacing it with a genuine Honda part restores accurate fuel delivery and brings the engine back to its intended operating condition.
