The Honda 16100-ZJ1-872 Carburetor Assembly (BG22M B) is a genuine OEM carburetor assembly designed for GX610 and GX620 horizontal shaft engines. As a direct Honda OEM component, this carburetor is built to the exact specifications Honda uses in production, ensuring correct jetting, fuel metering, and air-fuel mixture delivery without modification or guesswork. Confirm your engine's serial number against the fitment table before ordering — Honda supersedes carburetor assemblies at serial breaks, and the BG22M B variant designation identifies the precise configuration your engine requires. This part is the right choice for restoring clean, consistent fuel delivery to your GX610 or GX620 engine.
Key Features
- Correct Jetting and Fuel Metering — as a genuine Honda OEM carburetor assembly, this part carries factory-calibrated jets, needle settings, and emulsion circuits matched to the BG22M B specification, eliminating the tuning uncertainty that comes with an imprecise replacement
- Exact OEM Fit — engineered to the same tolerances as the original, this carburetor assembly mounts and connects to GX610 and GX620 engine fuel and intake systems without alteration
- BG22M B Variant — Verify Before Ordering — the BG22M B designation identifies a specific carburetor configuration; check the part number on your original carburetor and cross-reference your serial number with the fitment table to confirm this is the correct variant for your unit
- Restored Engine Performance — a worn or gummed carburetor causes hard starting, rough idle, and poor throttle response; replacing it with the correct OEM assembly brings fuel delivery back to specification and restores smooth, responsive engine operation
The carburetor assembly is responsible for mixing air and fuel in the precise ratio the engine needs to start, idle, and run under load. On GX610 and GX620 horizontal shaft engines, the carburetor draws fuel from the tank, meters it through calibrated jets and passages, and combines it with incoming air before the mixture enters the combustion chamber. When internal passages become clogged with varnish deposits, or when float valves and needle seats wear, the engine loses the ability to maintain a stable air-fuel ratio — leading to rough running, stalling, or failure to start. Replacing the assembly with a correct OEM unit restores the precise fuel control these engines depend on for consistent output.
