Re: Low vacuum
Vacuum leak somewhere?
Will it idle down further, say to 700-750? If it does, good indication of no vacuum leaks.
I suggested 8-9 jn./Hg of vacuum at idle because JohnZ offered this value sometime in the past.
I believe idle rpm is set around 900 rpm. If one revs up to say 1500, vacuum should come up. Throw a rag over the carb air horn and listen to what happens. If it dies,good setting, If ti revs up, vacuum leak or too lean.
