The Wacker Neuson is a genuine OEM Choke Shaft designed for GPS9700 and GS9.7V portable generators and PTS4V centrifugal trash pumps. As a direct OEM replacement, this part is sourced and manufactured to the same specifications as the original, ensuring proper choke lever travel and precise fuel-air mixture control on cold starts. Confirmed fitment spans multiple GPS9700 and GS9.7V generator configurations, as well as PTS4V and PTS4V(I) pump models. When your choke shaft is worn, bent, or broken, cold-start performance suffers — replacing it with part number restores full choke function quickly.
Key Features
- OEM-Spec Choke Control: — Manufactured to the original geometry so the choke plate seats and releases with the correct rotational travel — no binding, no slop.
- Genuine Wacker Neuson Part: — Sourced directly from Wacker Neuson, part number 5000116551 carries the same quality and traceability as the component that left the factory.
- Broad Model Coverage: — Fits GPS9700 portable generators (standard and premium configurations), GS9.7V generators with electric start, and PTS4V and PTS4V(I) centrifugal trash pumps.
- Restores Cold-Start Reliability: — A functional choke shaft allows the operator to restrict airflow correctly during cold starts; a worn or seized shaft can make starting difficult or impossible in cold conditions.
- Drop-In Replacement: — Dimensioned to match the original mounting bore and linkage connection points, so the shaft installs into the existing carburetor assembly without rework.
The choke shaft is the rotating rod inside the carburetor that controls the choke plate — the valve that temporarily restricts airflow to enrich the fuel-air mixture when starting a cold engine. When the operator engages the choke, the shaft rotates to close the plate; as the engine warms, it rotates back to the open position, allowing full airflow for normal running. A damaged or worn choke shaft prevents the plate from seating or releasing properly, leading to hard starting, rough idling, or an engine that floods and stalls until it reaches operating temperature.
