Unlike manuals for other makes, there is NO mention in the Packard shop manual for the V8s that the vacuum supply line should be disconnected and plugged when adjusting the ignition timing.

When I first started tinkering with V8 Packards, I did remove and plug that line when tuning the engine (with a timing light, dwell/tach meter, and vacuum gauge), but I later tried it with the line connected and got better results.
