The Wacker Neuson Spring/Choke Friction is a genuine OEM component designed for the BS50, BS60, and BS70 series vibratory rammers, as well as select BH series gas-powered breakers. As a direct Wacker Neuson OEM part, the is manufactured to the same specifications as the original, ensuring proper choke operation and consistent engine starting performance across a wide range of compatible machines. Fitment spans two-cycle and four-stroke BS rammer variants — including oil-injected and variable-speed models — making this one of the most broadly applicable choke system components in the Wacker Neuson rammer lineup.
Key Features
- OEM Spring Tension Integrity — Manufactured to the original spring rate specification, ensuring the choke plate returns to the correct position for reliable cold-start enrichment every time.
- Direct Drop-In Installation — Engineered to the same dimensions and hook geometry as the factory part, allowing straightforward swap-out within the carburetor choke assembly without additional hardware.
- Wide Rammer Family Coverage — Compatible with BS50, BS60, and BS70 two-cycle, four-stroke, and oil-injected vibratory rammer variants, as well as select BH series gas-powered breakers.
- Consistent Choke Engagement — A worn or broken choke friction spring causes erratic choke positioning, leading to hard starting, rough idle, and excessive fuel consumption; replacing it restores proper carburetor function.
- Fuel System Compliance — Correct choke spring tension is critical to maintaining the proper air/fuel ratio during startup, helping prevent over-richening conditions that can foul the spark plug or flood the engine.
The Spring/Choke Friction is a small but essential component within the carburetor choke assembly of a vibratory rammer or gas-powered breaker. Its job is to apply consistent friction or return tension to the choke plate, holding it in the correct open or closed position during engine startup and warm-up. When this spring weakens, breaks, or loses its tension, the choke plate can flutter or fail to hold position — causing hard starting, inconsistent idling, and poor throttle response. Replacing a faulty choke friction spring is one of the most straightforward carburetor service steps and restores proper engine starting behavior immediately.
