LB-1 Limiter Bushing Kit Instructions:
- Your kit contains two precision machined bushings. One larger 10 degree bushing with a small flat area machined on two sides and the other smaller bushing is the 14 degree that is round and has no flats.
- The 10 degree bushing will allow 10 degrees of mechanical advance and the 14 degree will allow 14 degrees of mechanical advance.
- The slot tolerances of the MSD Distributors are inconsistent and it’s possible that either bushing may be tight and possibly cause a slight bind. The bushing does not rotate, simply use a file or sand paper to remove enough material off each side of the bushing to allow for smooth operation of the advance mechanism.
- This sketch shows a simple exaggerated view of how to clearance the bushing if needed.
