Does that distributor have a grease cup on the side of it?
If it does, take off the cup and make sure that the spring and friction disc which rides on the distributor shaft are all there.
This assembly of parts is designed to put a specific amount of lateral pressure on the distributor shaft to eliminate shaft wobble, thus eliminating inconsistent points performance.
