The Wacker Neuson Starter Flap is a genuine OEM component designed for the BS50-4As, BS60-4As, BS62-4A, BS65-4As, BS68-4A, BS70-4As, BS72-4As, and related 4-stroke rammer series. As a direct OEM replacement, part is manufactured to the same specification as the original, ensuring proper seating, correct airflow restriction, and consistent pull-start behavior across the full range of compatible models. This starter flap covers an extensive lineup of Wacker Neuson 11-inch and 28-series rammers, including US, CN, and Sunbelt variants, so you can confidently source a single part across a mixed fleet.
Key Features
- OEM-Correct Flap Material and Geometry — Manufactured to the original specification for precise choke closure and airflow restriction, so cold-start performance matches what left the factory.
- Direct Drop-In Installation — Mounts to the carburetor throat in the same position as the original, requiring no trimming, bending, or adaptation to the existing linkage or housing.
- Broad Fleet Compatibility — Fits the BS50-4As, BS60-4As, BS62-4A, BS65-4As, BS68-4A, BS70-4As, and BS72-4As rammer families, including US, CN, and Sunbelt model variants.
- Consistent Cold-Start Enrichment — A correctly functioning starter flap delivers the fuel-rich mixture a cold engine needs; a worn or stuck flap leads to hard starting, excessive cranking, and unnecessary engine strain.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, part number 5100049187 carries the same quality assurance as the component originally installed on the production line.
The starter flap sits at the inlet of the carburetor and acts as a choke valve during cold starts. When closed, it restricts incoming air to create a richer fuel-air mixture, which allows the engine to fire and reach operating temperature more easily. Over time, the flap can warp, crack, or lose its ability to seat fully, resulting in poor cold-start performance, excessive pull-starting effort, and rough initial running — replacing it promptly restores normal starting behavior and protects the engine from unnecessary wear.
