It has sometimes been a practice to tap the needle (not too hard) to cause it to mate with the seat. (or, rather, form the softer seat to the steel needle). That can make it better or worse. Since you are going to some trouble here, you could bench test the carb for leakage, setting up a gravity feed tank (old lawn mower tank…) give it a couple of feet of head and see if it holds.
