Yes, it's generally recommended to disconnect the vacuum advance when setting the ignition timing on an engine. This ensures that you are measuring the base timing without any influence from the vacuum advance, which can vary based on engine load and speed. After setting the timing correctly, you can reconnect the vacuum advance to allow it to function properly during normal operation.
The timing should be set to Top Dead Center (TDC), but you must disconnect the electronic spark advance feature. Unfortunately, I don't know how to disconnect the spark advance. The timing chain is all that can be set. There is no way to set the timing as the distributor is not adjustable.
Disconnect and plug the vacuum line and time the engine. Reconnet the vaccum and recheck the timing which should be advanced.
