The Honda 16100-ZE3-F31 Carburetor Assembly (BE80D B/C) is a genuine OEM carburetor assembly designed for EG5000, EN3500, EN5000, EZ3500, and EZ5000 generators and GX340 horizontal shaft engines. As a direct Honda OEM component, this carburetor assembly carries the correct jetting, needle settings, and fuel metering calibration Honda specifies for these applications — no substitutions, no guesswork. Confirm your unit's serial number against the fitment table before ordering, as Honda supersedes carburetor part numbers at production breaks and the BE80D B/C variant designation identifies a specific configuration within this model family.
Key Features
- Correct Jetting and Fuel Metering — genuine Honda OEM construction means the main jet sizing, pilot circuit, and needle position match Honda's original specification for this carburetor variant, ensuring the engine runs at the air-fuel ratio Honda intended
- Variant-Specific Fit — the BE80D B/C designation identifies a specific carburetor configuration; verify your unit's carburetor type before ordering to ensure this assembly matches your machine
- Broad Application Coverage — fits EG5000, EN3500, EN5000, EZ3500, and EZ5000 generators and GX340 horizontal shaft engines; check the serial number on your unit against the fitment table to confirm the correct variant
- Restored Starting and Load Performance — a worn or gummed carburetor causes hard starting, rough running, and poor load response; replacing it with this OEM assembly returns clean fuel delivery and stable engine operation
The carburetor is responsible for mixing air and fuel in the precise ratio the engine needs to start, idle, and run under load. It meters fuel through calibrated jets and passages, responding to throttle position and engine demand to maintain consistent combustion. When a carburetor degrades — through varnish buildup from stale fuel, worn jets, or deteriorated gaskets and seals — the engine struggles to start, runs erratically, surges at load, or stalls outright. Replacing the assembly with a correct OEM unit restores the fuel delivery the engine depends on to produce steady power output.
