I honestly believe there was some type of casting defect or whatever, and there were known problems with the Avenger carbs at the time, specifically the 670s.
I went thru all the passages poking them w safety wire, but never really found a smoking gun.
I had an 870 on my LeMans, and that ran very well.
I suspect if I would have stuck with diags of the 670 I could have got it running right, but I had spent so much time on it already I was done. It just shouldn't have required that much effort IMO.
