Witti had the same problem I'm having about a year ago, I found out, after doing an extensive forums search. FsT4WrD told him to change pilots to a 33.5, but that seems like a huge jump to me. So I'm waiting on verification from FsT or Witti before I go running out to buy pilots at $9 a pop. CT said to move the clip on the needle, and turn the air screw out a turn, but I have a feeling I'm gonna do it for nothing, like Witti.
