Carter AFB/340 Tuning
accepted.
Really, try cruising 1st to get the rod size right, these thngs tend to be lean out of the box, at least was on a 340 cam'd 318.
My rule of thumb for these carbs [600-625 afb/eddy] is to set them up like the torker version which was what I was referencing with the 100-73/47 deal
springs n such need driving to figure out.jmo
good luck.
