General information about this item
Product info
The idle tube retaining screw B7-03-231, size 55, secures the idle tube in the Zenith KL 10/11 carburetor of the BMW 700 Engine 425 or Kraka and ensures a tight, stable idle channel. During restoration, worn or corroded original screws are replaced with this replacement part to prevent idle fluctuations and air leaks. This ensures that the carburetor’s idle adjustment remains consistently reproducible.
