The Honda 16015-ZN1-003 Float Chamber Set is a genuine OEM component designed for GX670 horizontal shaft engines and GXV670 vertical shaft engines. As a direct Honda OEM part, this Float Chamber Set is manufactured to the same specifications as the original, ensuring correct fuel bowl volume and float function for consistent carburetor performance. This part is the correct replacement for both the GX670 and GXV670 platforms — verify your engine model and serial number against the fitment table to confirm the right application before ordering.
Key Features
- Genuine OEM Fuel Bowl Fit — sourced directly from Honda, this Float Chamber Set matches the original carburetor bowl geometry for a proper seal and correct fuel capacity on GX670 and GXV670 engines
- Accurate Fuel Metering — a sound float chamber maintains the correct fuel level in the carburetor; a cracked, leaking, or deteriorated chamber causes rich running, flooding, or hard starting
- Dual-Platform Coverage — fits both the GX670 horizontal shaft engine and the GXV670 vertical shaft engine; confirm your model before installing, as crankshaft orientation affects carburetor mounting
- Serial Number Verification Recommended — Honda supersedes parts at production breaks; check your engine serial number against the compatibility table to ensure part number 16015-ZN1-003 is current for your unit
The float chamber is the lower bowl section of the carburetor that holds a small reservoir of fuel at a precisely controlled level. A float and needle valve work together to admit fuel as it is consumed and shut off flow when the correct level is reached — the chamber itself is what contains that reservoir and seals it from leaks and debris. When the chamber cracks, warps, or develops a compromised gasket seating surface, fuel can leak externally or the float level shifts, causing flooding, fuel starvation, or an engine that runs unevenly and refuses to hold a steady speed.
