Lister HR & HRW Inlet Valve Lister P/N 351-50420

I purchased the points set for a Wipac Series A magneto. I found that the plastic / composite material that the metalwork was mounted on was rubbing on a screw head on the magneto. I had to gently file the plastic away till it no longer caught on the screw head. Check before using that the moving points will not touch any other component.
