Hitachi 669-8816 — Carburetor packing (genuine Hitachi/Hikoki)

- Description: A genuine Hitachi carburetor packing (part number 669-8816). This thin sealing gasket sits between the carburetor and mating surface to prevent air and fuel leaks, restore proper engine idle and throttle response, and is supplied as a single replacement packing.

- What it is good for: Designed for small two‑stroke Hitachi/Hikoki/Tanaka outdoor‑power engines, this packing is used when a worn or damaged carburetor gasket is causing hard starting, poor idling, fuel seepage or loss of power. Multiple spare‑parts suppliers list this exact part number as the carburetor packing for Hitachi/Hikoki family engines.

- Example tool families (where similar carburetor packings are used): While manufacturers’ public fitment lists for 669‑8816 are limited, these types of carburetor packings are commonly used on Hitachi two‑stroke trimmers and brushcutters in the CG‑series (for example CG22 / CG24 family) and on small handheld blowers and similar units—so if your tool is a Hitachi/Hikoki/Tanaka 21–27 cm³ two‑stroke trimmer or blower, this is the part typically referenced for carburetor repairs. (Please confirm the part number against your tool’s parts diagram or stamped part label before fitting.)
