The Honda 16100-ZE3-V21 is a genuine OEM Carburetor Assembly (BE80C B) designed for GX340 horizontal shaft engines. As a factory-original component, this carburetor assembly is manufactured to Honda's exact specifications, ensuring the correct jetting, fuel metering, and air-fuel calibration for the GX340. Honda supersedes carburetor assemblies at serial number breaks, so verify your engine's serial number against the fitment table before ordering to confirm part number 16100-ZE3-V21 is the correct match for your unit. A direct-fit replacement, this assembly installs in place of the original without modification.
Key Features
- Correct Jetting and Fuel Metering — as a genuine OEM carburetor assembly, this part delivers the exact air-fuel ratio the GX340 engine is calibrated for, supporting clean starts and consistent power output across the rpm range.
- Direct OEM Replacement — built to the same specifications as the original carburetor assembly, this part installs using the existing mounting points and hardware with no adaptation required.
- GX340 Fitment — designed specifically for GX340 horizontal shaft engines; check your engine's serial number against the fitment table to confirm this is the correct carburetor assembly variant for your production run.
- Restored Engine Performance — a worn or failing carburetor causes hard starting, rough running, and poor fuel economy; replacing it with the correct OEM assembly brings the engine back to its proper operating condition.
The carburetor is responsible for mixing fuel and air in the precise ratio the engine needs to start reliably and run efficiently under load. On GX340 horizontal shaft engines, the carburetor assembly meters fuel through calibrated jets and circuits that are matched to the engine's displacement and governor settings. When a carburetor wears out or becomes fouled — through varnish buildup, worn needle seats, or damaged gaskets — the engine may surge, run rich or lean, lose power, or refuse to start; replacing the assembly with the correct OEM unit restores proper combustion and full engine output.
