The Honda 16200-ZG8-812 Solenoid Valve Assembly is a genuine OEM component designed for GX640 horizontal shaft engines. As a direct OEM replacement sourced from Honda, this part is built to the same specification as the unit that left the factory, ensuring correct fit and function without adaptation. Honda supersedes parts at serial-number breaks, so confirm your engine's serial number against the fitment table before ordering to make sure part number 16200-ZG8-812 is the right unit for your machine.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this assembly meets the same fuel-shutoff and metering tolerances as the original, maintaining the fuel delivery integrity your GX640 depends on.
- Exact Solenoid-to-Carburetor Interface — engineered to the original connector and thread specification, this part installs directly in place of the factory unit on GX640 horizontal shaft engines with no rework needed.
- Serial Number Verification Recommended — Honda revises solenoid valve designs at production breakpoints; check your engine's serial number against the fitment table to confirm this assembly applies to your unit.
- Restored Fuel Shutoff Function — a failed solenoid valve can cause hard starting, rough running, or an engine that won't shut off cleanly; replacing this assembly restores proper fuel control to the carburetor circuit.
On GX640 horizontal shaft engines, this component sits on the carburetor body and operates each time the engine starts and stops. When the solenoid coil weakens or the valve tip wears, the engine may refuse to start, run erratically, or continue to run after the key is turned off. Replacing the assembly with a genuine OEM unit restores the precise electrical and mechanical response the fuel system requires.
