The Honda 16100-Z1A-812 Carburetor Assembly (BB61N B) is a genuine OEM Carburetor Assembly designed for the GC190 horizontal shaft engine. As a factory-sourced component, this carburetor assembly is built to Honda's own specifications, ensuring the correct jetting, needle geometry, and fuel metering for the GC190. Confirm your engine's serial number against the fitment table before ordering to make sure part number 16100-Z1A-812 is the right application for your unit.
Key Features
- Correct Fuel Metering — as a genuine OEM assembly, this carburetor carries the exact jetting and circuit calibration Honda specifies for the GC190, so the engine receives the right air-fuel ratio across its operating range.
- Direct OEM Replacement — engineered to drop into the GC190 horizontal shaft engine in place of the original, using the existing mounting points and fuel and throttle connections.
- GC190 Fitment — designed specifically for the GC190 horizontal shaft engine; verify your serial number against the fitment table, as Honda supersedes carburetor assemblies at serial breaks.
- Restored Engine Performance — a worn or varnished carburetor causes hard starting, rough idling, and poor throttle response; replacing it with this assembly brings fuel delivery back to specification.
The carburetor is responsible for mixing air and fuel in the correct ratio before the mixture enters the engine's combustion chamber. On the GC190 horizontal shaft engine, the carburetor meters fuel through precisely sized jets and circuits calibrated for that engine's displacement and speed range. When a carburetor wears, clogs with varnish deposits, or develops internal leaks, the engine struggles to start, runs rough at idle, surges under load, or loses power — symptoms that a direct carburetor replacement resolves by restoring accurate fuel delivery from the first start.
