Here's what you can do to check the distributor:
Simply gap the points at .016" at the cam peaks. Make sure an Ohm meter will see contact when points are closed, the continuity will break when open. Many times new points are so corroded you need to file them before they will make contact. Then Ohm the wire from the coil to the distributor. The best overall Ohm test is from the coil connection to the steel plate on the points. Open is open, closed shows continuity.
