OK-I went out yesterday and purchased a Mityvac-hand vacuum pump. I measured 14-11 in on the intake manifold. If I remove the air filter it will slowly die. I also checked out the vacuum advance and was never able to get a reading/nor any action on the breaker plate. I capped off the vacuum advance and took it for a ride-it did not die but it was barely running. I hooked the line back to the vacuum advance and took it for another ride-did not die.
I also put a new coil on it which seems to help-not too sure why.
If I start it in the driveway-it will idle all day. It only happens after driving and coming to a stop.

The carb and fuel pump were rebuilt in 2006 by local Packard wizard-Mark Lambert.

thoughts appreciated
