"Two of the jets on one carb are different, I just figured they would be the same and took them both out and now need to figure which one goes where. I am not sure what these jets are called but have attached a picture. Can someone tell me where the larger of the jets might go? The only clue I have is that one of the air neeedles was backed out a little more from bottom than the other. One jet is a .028 and the other is a .032. On the top carb, they are both .052 and on the middle carb they are both .028. I feel it is probably a tuning thing done from the factory, any help would be appreciated.

Is this typical or was it a tuning issue from the factory? Does it have to do with the air screw adjustment?
