They are stamped. The odd thing is the car ran great until last saturday with this setup. The jets have never been changed. I don't know if you received my PM but I did notice that the 2 outside air screws were tightened all the way down and the 2 inside carbs were a 1 1/2 turns out. I have always ran them 1 1/2 turns out. I do know with a little research today that they are honda jets, not holley and they only offer a 105 110 115 and 120. Thanks again for all your help.
