The Honda 16013-Z0A-004 Float Set is a genuine OEM component designed for GCV520, GCV530, GXV520, and GXV530 vertical shaft engines. As a factory-original part, it is manufactured to the same tolerances as the float set installed at the factory, ensuring proper fuel metering and carburetor function are restored exactly as Honda intended. This Float Set is the correct replacement when the original float is saturated, damaged, or causing fuel delivery issues in these engines. Always confirm your engine's serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks within the same model family.
Key Features
- Correct Fuel Metering — as a genuine OEM float set, it maintains the precise buoyancy and pivot geometry Honda specified for these carburetors, preventing rich or lean fuel conditions that degrade engine performance
- Direct OEM Replacement — this part is built to Honda's original specifications, dropping directly into the carburetor in place of the worn or failed original with no modification needed
- Broad Vertical-Engine Coverage — fits GCV520, GCV530, GXV520, and GXV530 vertical shaft engines, covering both the residential GCV and commercial GXV lines in this displacement range
- Serial Number Verification Recommended — Honda updates parts at production serial breaks, so confirm your engine's serial number against the fitment table to ensure this is the correct float set for your unit
As fuel is consumed, the float drops and opens the needle valve, allowing the bowl to refill; when the correct level is reached, the float rises and closes the valve, cutting off the flow. This balance keeps the air-fuel mixture within the narrow band the engine needs to run cleanly and efficiently. A float that has become waterlogged, cracked, or deformed can no longer hold its correct position, causing the bowl to overflow and flood the engine, or starve it of fuel — leading to hard starting, rough running, or a persistent fuel smell.
