Okay, I have looked at all the pics, links, and done the reading, but I want to make sure I am drilling the right thing out to get to the screws I need to. In the pics, they are located right next to the vacuum lines correct? And both carbs are the same? Also, when I marbeled, do I need to remove and plug the small vacuum line to the air box as well, or just the lines to the reeds? I'm thinking for me the stupid question is the one I fail to ask! Thanks!!!!
