The Honda 16100-Z0S-931 is a genuine OEM Carburetor Assembly (BE61K A) designed for GX120 horizontal shaft engines. Sourced directly from Honda, this assembly carries the correct jetting, emulsion circuits, and metering specifications for the GX120 — ensuring the engine receives the precise air-fuel mixture it was engineered to run on. Honda supersedes carburetor assemblies at serial number breaks, so verify your engine's serial number against the fitment table before ordering to confirm this is the right variant for your unit.
Key Features
- Correct Jetting and Fuel Metering — as a genuine OEM assembly, this carburetor carries Honda's specified jet sizing and needle seat geometry for the GX120, so the engine runs at the mixture ratio Honda engineered it for
- Direct OEM Replacement — this assembly replaces the original unit on GX120 horizontal shaft engines and installs using the existing mounting hardware and linkage connections
- Variant-Specific Fitment — the BE61K A designation identifies this as a specific carburetor variant within the GX120 lineup; check your engine's serial number against the fitment table to confirm this variant matches your unit
- Restored Throttle Response and Starting — a worn or degraded carburetor causes hard starting, rough idle, and poor throttle response; replacing it with this assembly brings fuel delivery back to spec
The carburetor is responsible for mixing air and fuel in the correct proportion before that charge enters the engine's combustion chamber. On a small horizontal shaft engine like the GX120, the carburetor controls everything from idle speed and cold starting to full-load fuel delivery — making it one of the most performance-critical components on the engine. When a carburetor wears, clogs, or develops a compromised needle seat or float, the engine may run lean or rich, surge at idle, refuse to start, or lose power under load. Replacing it with the correct OEM assembly restores the fuel circuit to Honda's original calibration.
