The Honda 16166-Z8T-WB1 Main Nozzle is a genuine OEM component designed for GX340 horizontal shaft engines. As a direct Honda OEM part, it is manufactured to the same specification as the original and is sourced through an authorized Honda parts network. This nozzle is confirmed for GX340 engines — always cross-reference your engine's serial number against the fitment table to ensure part number 16166-Z8T-WB1 is correct for your specific unit, as Honda supersedes carburetor components at serial breaks.
Key Features
- Correct Fuel Metering — as a genuine OEM main nozzle, this part delivers the precise orifice dimensions that govern fuel delivery in the main circuit, keeping air-fuel ratio within Honda's intended range for the GX340
- Direct OEM Replacement — this nozzle drops into the carburetor body without modification, restoring the original fuel circuit exactly as Honda designed it
- GX340 Fitment — confirmed for GX340 horizontal shaft engines; check your serial number against the fitment table before ordering, as carburetor components can vary across production runs
- Restores Clean Running — a worn, clogged, or damaged main nozzle causes rich or lean running, poor throttle response, and fuel consumption issues; replacing it with a genuine part brings the engine back to proper operation
The main nozzle is a precision metering component inside the carburetor responsible for controlling the volume of fuel drawn into the airstream during mid-range and full-throttle operation. It works by allowing a calibrated amount of fuel to mix with incoming air as it passes through the venturi, producing the combustible mixture the engine needs to run efficiently. When the nozzle becomes clogged with varnish deposits, worn, or damaged, the engine will typically run rough, hesitate under load, or exhibit poor fuel economy — symptoms that a genuine replacement nozzle directly addresses.
