General information about this item

Product info
The B7-03-013 return spring for the throttle valve in the BMW 700 ensures that the throttle valve reliably returns to the idle position after the accelerator pedal is pressed and that the linkage closes without play. When restoring the carburetor, a fatigued or corroded spring must be replaced to prevent stalling and rough idling.
