From what I'm reading you used the NuRex without the distributor body in place and put the pointer on the NuRex wrench against the #4 spark plug.
If so you will need to re-set the timing again WITH the distributor body in place and put the pointer on the NuRex wrench against the post on the distributor body that the wire for #4 spark plug attaches to.
Instead of using the timing pin to find the dimple I always use a short phillips screw driver to find the dimple.
