Ahs, The small wire, b to c is a breaker plate ground. Wire d should be the one to the coil. Check the point wire d, to see that it wont bind when the plate advances. You may want to move the ground wire to the hole closer to the vac adv.
Great, so both wires are connected to the correct positions, right? I will make sure there is no binding going on.
When you suggest moving the breaker plate ground wire to hole closer to the vac adv, which position should be moved? B or C? Is only one end moved? Or both?
And sorry, yes, point D goes to the IGNITION coil not the distributor
