It doesn't do this terribly consistently, as it seems to at times blip when going down to 44 and then want to pulsate around the 40 like I would want to see it do, but it will then either go back to the high and wide range pulsating or just hold steady at 44.
Early dwell measurements and other observations were pointing to my car being set rich, so I intended on leaning it out slightly. Upon removing the rubber plug, I could hear a distinct change in engine performance (affect from the vacuum leak?).
I did make a small adjustment to the mixture screw, and would consider it "two hours" counterclockwise, in the sense that when I secured the 3 mm hex wrench, the handle was aimed at 10 pm and I went down to 8 pm (understandable?). I could put it back as it was easily if need be.
