I tried to follow the Chilton guide in tuning up my ‘68 Mustang, 289 bored out to a 302. It said the advance should change with an increase in engine RPM. It does. It said the advance should change differently with the vacuum hose disconnected. It changes the same at all RPM’s whether the vacuum hose is on or off. When I disconnect the vacuum hose and put my finger over it I can feel a vacuum from the carburetor.
Do distributor vacuum advance diaphragms fail? If so, can they be replaced or can the vacuum advance be replaced or do I need to replace the entire distributor?
What happens if a drive with a failed vacuum advance diaphragm?
