What happens when I remove the vacuum line which comes?
The points electrically control the initiation of the spark. As vacuum increases the lever moves the points and advances the timing of the spark. If you remove the vacuum you are negating this necessary automatic adjustment of the spark ignition circuit. , Natural born engineer, PE.
When do you disconnect the vacuum hose from the distributor?
The distributor has a mechanical and vacuum controlled timing advance in/at the distributor . You disconnect the vacuum hose to adjust/ check the ignition timing . When finished , you reconnect the vacuum hose and set the base idle speed . Your “ experiment “ of disconnecting / plugging this hose will decrease power & gas mileage .
Where does the vacuum advance line come from?
Many people think the vacuum advance line comes directly off the manifold below the throttle plates. This is not so. If it did, maximum advance would occur at engine idle- that is far too advanced for an idle setting.
Where is the vacuum port on a Locati?
The vacuum port is actually located slightly above the throttle plate, so maximum vacuum (and vacuum advance) occurs at part throttle (cruising down the highway). With the port in that particular locati Plugging the vacuum advance prevents an additional advance from happening at part throttle (low load), like while cruising down the road.

What happens when a vacuum hose goes bad?
When a vacuum hose breaks, becomes disconnected or has a leak, it can cause multiple mechanical failures, from simple engine misfires to causing full system shutdown.
