The Honda 16010-ZN1-802 Gasket Set is a genuine OEM component designed for GX670 horizontal shaft engines and GXV620 and GXV670 vertical shaft engines. As a direct Honda OEM part, this gasket set delivers the exact material grade and dimensional accuracy needed for a proper seal — no guesswork on thickness, port sizing, or compatibility. Confirm your engine's serial number against the fitment table before ordering, as Honda updates part supersessions at production breaks. This part is the right call for any rebuild, top-end service, or fuel system overhaul on the covered models.
Key Features
- OEM Sealing Integrity — engineered to Honda's own specifications for fuel and air passage sealing in the carburetor circuit, so gaskets compress correctly and hold without weeping or leaking under normal operating temperatures
- Direct OEM Replacement — sourced directly from Honda, part number 16010-ZN1-802 replaces the original set with no fitting adjustments needed
- Broad Engine Coverage — fits GX670 horizontal shaft engines and GXV620 and GXV670 vertical shaft engines, covering a range of high-displacement Honda twin-cylinder applications
- Serial Number Verification Recommended — Honda supersedes gasket sets at specific production breaks, so always match your engine's serial number to the fitment table to confirm this is the correct set for your unit
- Restored Fuel System Performance — worn or deteriorated carburetor gaskets allow air leaks and fuel seepage that cause hard starting, rough idle, and poor fuel metering; replacing them with this set returns the carburetor to proper operation
A gasket set for the carburetor circuit provides the sealing layers between the carburetor body, its bowl, and the engine intake — preventing unmetered air from entering the fuel charge and stopping fuel from leaking at mating surfaces. On a large-displacement twin-cylinder engine like the GX670, GXV620, or GXV670, even a minor air leak at these joints disrupts the fuel-to-air ratio enough to cause rough running, hunting at idle, or difficulty starting. Over time, heat cycling causes the original gaskets to harden, compress, or crack, making periodic replacement a standard part of carburetor service and rebuild work.
