The Multiquip 16628ZJ1850 Choke Knob Rod is a genuine OEM component designed for GA9.7HE, AR13H, AR13HA/HAR, and AR13HC series equipment. Sourced directly from Multiquip, this rod delivers an exact fit to the GX610K1QZB engine configuration found across these machines. As a genuine OEM part, 16628ZJ1850 meets the original design specifications — so you get the correct geometry, material grade, and connection points without guesswork. Confirm your model code against the fitment list before ordering to ensure compatibility.
Key Features
- Genuine OEM Construction — Manufactured to the original dimensional and material specification for the GX610K1QZB engine, ensuring the rod operates correctly within the choke linkage assembly.
- Direct Drop-In Fit — Connects to the existing choke knob and carburetor linkage points without reworking brackets or hardware, restoring the linkage to its original configuration.
- Broad Model Coverage — Compatible with GA9.7HE gasoline-powered generators and AR13H, AR13HA/HAR, and AR13HC asphalt ride-on rollers.
- Consistent Choke Response — A correctly seated choke rod allows smooth, full-travel choke engagement and release, supporting clean cold starts and proper engine warm-up cycles.
- Fuel System Integrity — A bent, worn, or missing choke rod prevents accurate choke positioning, which can cause hard starting, rough running, or excessive fuel draw — replacing it promptly restores normal engine behavior.
The choke knob rod is the mechanical link between the operator-facing choke knob and the carburetor's choke valve. When you pull or rotate the choke knob, this rod transfers that motion directly to the choke plate, restricting airflow to enrich the fuel mixture for cold starts. If the rod is bent, cracked, or disconnected, the choke plate cannot be positioned correctly — resulting in difficulty starting, poor idle, or an engine that floods under cold conditions. Keeping this linkage intact is a straightforward maintenance step that has a direct impact on reliable engine starting.
