Hg (inches of mercury) of vacuum during light load, but this will drop below 5 in. Venturi vacuum was used before distributors had mechanical advance as it was a increasing vacuum signal as the engine ran faster and faster. Yes, i'm trying to figure out if something is keeping the engine from producing enough power at that low of an rpm that the.
