A distributor vacuum advance uses engine vacuum acting on a diaphragm to advance ignition timing through the distributor. It typically adds advance at light throttle, when vacuum is high.
Signs a vacuum advance may need replacing include hesitation or sluggish response at part throttle, reduced fuel economy, or a diaphragm that will no longer hold vacuum. Timing and vacuum-hose problems can cause similar symptoms, so diagnose the cause first. If the original vacuum advance has failed, the VC-230 replaces it.
