[Custom/Ten]

The thing that had me most confused about the idle screw is that when I go to far in/clockwise the tailpipe starts to get a little smoke out of it. You can hardly see it but it looks to be a little bit black. Maybe it's grey, does that make sense/sound normal, is that what happens when you idle to lean? I was thinking that meant it was rich and that's most of the reason other threads were confusing me and why I wanted to start a thread for the Rochester but sounds like it works about the same as any other carb.
