I have been helping a friend with his 122 that is having issues with the points on his original B18 distributor closing to down to .012 from the initial set point of .016 in a matter of minutes after running the engine. The dwell goes from 60 degrees to almost 70 degrees. This is a new problem that has arisen recently as the car has been used as a daily driver for the better part of 4 years. In an effort to fix the problem he ordered a set of points from IPD and made sure to lube the contact point between the cam on the distributor and the points themselves. This has not helped. My first thought was that he was not tightening down the set screw tight enough, but after checking it is as tight as it can go.

Any ideas? Thanks in advance.
