This is a potentially very useful thread. Parsed by carb type it might one day make for a handy reference database of best proven practices. Shame the old thread got lost in the shuffle.
Just as a sort of baseline, I wonder if someone could provide the stock Mikcarb VM28 and other carbs' factory setup(s) through the years with the stock exhausts, both with and before the Air Pulse Valve, "Catalytic" Tube, and so forth were added.
