what would one expect for a vacuum gauge reading at idle for a 8.2 MPI Crusader engine.
Both of mine read 12 at idle, which seems low. I have read that low consistent idle may indicate retarded ignition timing. Should one use a vacuum gauge in conjunction with a timing light when setting the initial timing? Needle vibrates very little which I understand is ok with these type engines and their valve overlap.
