It's not so much the "looseness" you need to be concerned with, it's more about the shape of the holes. If egg shaped they are worn, if round they are probably fine. I rebush them all anyway so it's no matter to me. BTW, the EB is basically the same carb, however they did make a few design changes to the casting, one of the changes made makes the typical method of rebushing them impossible due to the length of the shaft/tube casting.
