If you turn carburetor upsike down and watch the butterflies open, you will see that the progression holes are not opened in sequence. All three are open to the vacume at the same time so I do not think it matters to much if at all. The size of the hole certainly does matter. 12 o'clock seemed to work for me, but I think 2 o'clock will also work. I used 12 because it was easy to eyeball that location from carb to carb.
Lets hear your thoughts.
Bill,

Others will agree that all of the progression holes are exposed one at a time.

I have 2 carbs that have a threaded port and 2 carbs that are plugged and I don't know if they are threaded behind the plug or not. Any ideas?
I'd say a plugged progression port would have no threads, cheaper to make.
