Make sure the firing order is correct...
A way to determine a vacuum leak is to squirt brake cleaner at the suspected areas and listen to see if there is a change in the sound of the engine. The cleaner is flammable so be careful.
At the distributor remove the vacuum line and plug. Then see if there is a change in the readings.

You can also remove the distributor cap and attach a vacuum pump to a line attached to the advance, pull in some vacuum and see if the plate the points ride on moves and stays moved. If the plate moves back there is a hole in the diaphragm.

Maybe a leak in the carb to manifold gasket.

Just some more ideas....
