The Honda 16674-Z5V-800 Choke Rod is a genuine OEM component designed for GXV390 vertical shaft engines. As a direct Honda OEM part, it is manufactured to the same specifications as the original, ensuring a correct fit without modification. This part is built for GXV390 engines, so confirm your engine's serial number against the fitment table before ordering. Honda supersedes parts at production breaks, and verifying your serial number is the single most reliable way to make sure part number 16674-Z5V-800 is the right choice for your unit.
Key Features
- Genuine Honda OEM Quality — manufactured to Honda's original specification for the choke linkage, ensuring the choke valve opens and closes with consistent travel and positive engagement every time
- Direct Replacement for GXV390 — designed specifically for GXV390 vertical shaft engines, this rod connects the choke actuator to the choke valve with an exact-fit interface that keeps linkage geometry correct
- Serial Number Verification Recommended — Honda updates parts across production runs, so match your engine's serial number to the fitment table to confirm this is the correct rod for your specific unit
- Smooth Cold-Start Performance — a worn or bent choke rod allows the choke valve to sit in an incorrect position, leading to hard starts, rough warm-up, or an engine that floods; replacing this part restores crisp choke action and clean starting behavior
The choke rod is a mechanical linkage component in the fuel system that connects the choke actuator — whether operated by hand, a primer system, or an automatic choke mechanism — to the choke valve inside the carburetor. When the engine is cold, the choke valve partially restricts airflow to enrich the fuel mixture, giving the engine the richer charge it needs to fire reliably. As the engine warms, the choke opens to restore normal air-fuel balance. A damaged or missing choke rod breaks this mechanical connection entirely, leaving the choke valve uncontrolled and making reliable cold-starts impossible.
