The Honda 16100-ZH8-D21 Carburetor Assembly (BE51A B) is a genuine OEM replacement built for GX160 horizontal shaft engines, EB2200 and EB2500 inverter and conventional generators, and EM1600, EM1800, EM2200, and EM2500 generators. As a direct Honda OEM component, this carburetor assembly carries the exact jetting, metering circuits, and bowl geometry Honda specifies for the BE51A B variant — no substitution or adaptation needed. Confirm part number 16100-ZH8-D21 against your machine's serial number before ordering, as Honda supersedes carburetor assemblies at specific production breaks.
Key Features
- Exact Jetting and Fuel Metering — genuine OEM construction means the main jet sizing, pilot circuit, and needle position match Honda's original specification for the BE51A B carburetor, so fuel delivery is correct from the first start
- Variant-Specific Fit — the BE51A B designation identifies this as a specific carburetor variant; verify this matches your unit's existing carburetor before installation, as other variants are dimensionally similar but not interchangeable
- Broad Fitment Across Honda Generator and Engine Lines — fits GX160 horizontal shaft engines as well as EB2200, EB2500, EM1600, EM1800, EM2200, and EM2500 generators; check your serial number against the fitment table to confirm the correct supersession for your production run
- Restores Clean Running — a worn or gummed carburetor causes hard starting, rough idle, and loss of output power; replacing it with this OEM assembly returns the engine or generator to stable throttle response and consistent power delivery
The carburetor assembly 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 circuits, responding to throttle input and engine demand to maintain consistent combustion. When a carburetor degrades — through varnish buildup, worn jets, or damaged gaskets — the engine struggles to start, surges at idle, or runs lean under load, reducing power output and risking overheating. Replacing the assembly with a genuine OEM unit restores the original fuel delivery characteristics Honda engineered into these engines and generators.
