J, If the rotor is pointing to a location between the terminals when the spark happens, there is an issue. The distributor cam (on this distributor) is on the same shaft as the rotor notch/flat that indexes the rotor. If the points are the wrong ones (even if they fit on the backing plate) the rubbing block will be in the wrong place. This can be one cause of that wrong rotor position. The wrong rotor can also be blamed for the issue fitting is not the same as indexed. a cap that fits is also suspect for displaced terminals. The rotor will fail if the spark needs to jump 1/2" every time it fires. The rotor tip should be within its width pointing to the terminal, as the points break. If not is is wrong. JimN
