Check the "static' timing by setting the idle RPM's to specs (about 550 RPM's) then disconnect the vacuum hose from the dizzy.
If you want to check the "total advance" leave the vacuum hose connected and rev the engine to about 3,000 RPM's and either read the timing light gauge OR what's on the timing tape/marks on the balancer (if so equipped).
Check the mechanical advance by disconnecting the vacuum and reving to 3K and reading the light or the timing tape.
