Hey everyone, first a disclaimer:
The vacuum gauge shown in my video, I just got today. It's old, abused, and looks like hell, but it is a Snap-on. Maybe from the 70's. I dunno. Anyway...
I hooked it up to a vacuum source on my 292 and got 5 inches when cold and 7 when it warmed up. I do have a booster for my windshield wipers. That only reads 10 inches. The video shows me idling at about 600 to 700 rpm.
So, is that low of vacuum possible? The engine idles fine, it does have a stutter and sometimes stall at acceleration from a dead stop (still diagnosing that) but once it's on the highway she accelerates fine. Could my gauge be shot? Could there be a vacuum leak? Any other ideas?
