OK, so I must have been hallucinating when I told you I had a secondary metering block. I don't, mine is a standard 3310-11. Maybe too many gas fumes.
I hooked up the vacuum gauge this PM and played with the idle mixture a bit. Leaned it out a touch (1/8 turn on both screws). Vacuum gauge bounces a bit as I have some roll to my idle. Should I turn up the idle to reduce the roll while adjusting the idle mixture so it is easier to see the gauge change?
Also, when I went to hook up the gauge, I noticed that the rubber cover to that front vacuum fitting was missing. I will get a replacement, but am curious as to what effect that missing cover has had? Car runs great, other than sometimes dieseling a bit when I shut it off, which is what I am trying to solve.
