Default Vacuum advance

Adjusted the ignition timing today, and found that there is no difference in idle with the vacuum hose connected to the carburator or not. When accelerating, the ignition advances, which is probably due to the flyweights.
When is the vacuum advance part suppost to do something? Is there any way to test the vacuum advance bellow without having a vacuum source?
