Sorry, I don't know what the idle mix screws are set at. How do I determine this? I believe that the carb might be a '68; however, I am not sure. The original Lemans 350 had a 2bbl. Many years ago, I purchased a period correct intake and a reconditioned period correct quadrajet. I now have an Eldebrock aluminum intake with the old carb. The carb is tight. Most of the vacuum tubes had been removed when I bought the car. They are plugged in all places. The 350 ran good with the same set up. I have attached a couple of photos so you can see what I am working with. Thanks.
