The Honda 16100-Z6P-803 Carburetor Assembly (BK07M B) is a genuine OEM carburetor assembly designed for GXV630, GXV660, and GXV690 vertical shaft engines. As a direct Honda OEM component, this carburetor assembly is engineered to the exact specifications Honda set for these engines, ensuring correct fuel metering, air-fuel ratio, and throttle response straight out of the box. The BK07M B designation identifies this as a specific carburetor variant — confirm this matches the carburetor on your engine before ordering. Honda supersedes carburetor assemblies at serial number breaks, so cross-reference your engine's serial number against the fitment table to confirm part number 16100-Z6P-803 is correct for your unit.
Key Features
- OEM Fuel Metering Accuracy — calibrated jets, needle settings, and emulsion circuits match Honda's original specification for the GXV630, GXV660, and GXV690, so fuel delivery and idle quality are restored from the first start
- Variant-Specific Fit — the BK07M B designator identifies a distinct carburetor configuration; verify this variant matches your engine's original carburetor before installing
- Serial Number Verification Recommended — Honda issues carburetor supersessions at production breaks, so check your engine's serial number against the fitment table to confirm this is the correct assembly for your unit
- Engine Performance Restored — a worn or damaged carburetor causes hard starting, rough idling, fuel flooding, and power loss; replacing it with the correct OEM assembly returns the engine to its designed operating condition
The carburetor is responsible for mixing air and fuel in the precise ratio the engine needs to run cleanly and efficiently. On the GXV630, GXV660, and GXV690 vertical shaft engines, it meters fuel through calibrated jets and circuits that govern idle speed, mid-range response, and full-throttle output. When a carburetor wears out, becomes gummed with stale fuel deposits, or develops internal damage, the result is hard starting, erratic idle, fuel-rich running, or a complete inability to run — replacing it with the correct OEM assembly is the most reliable way to restore consistent, full-power operation.
