Okay, so I moved my needle down or moved my clip up two notches how ever you want to look at it. So now I am having a tuff time trying figure out if I changed my bottom or top. What end does moving the needle affect? I know my bottom has a lean condition but since I moved the needle it seems to have cleaned up a messy condition I have been having from 1/8 up to 1/2 throttle. Oh and I have a 01 rm 250 with 46 p 162 m air screw 2 turns choke idle 12 clicks out fresh top end and drool dripping out the pipe? It seems to run Lean on bottom and rich on top.
