Does the vacuum advance diaphragm hold vacuum? Is its return
spring broken?

Does the advance unit's rod (connected to the distributor base
plate internally) move when you suck on the hose?

Does it hold its vacuum when you manage to block off the tube
with a finger while under vacuum?

Does the base plate return to its rest position when the vacuum
on the diaghragm is released?

The original diaghrapm will be well past its use-by date. The
base plate may be binding for whatever reason.
