Alright, I'll try that. The weird thing is it's been showing signs of both lean and rich. The plug looks good, but back when I had a small intake leak, it ran better. I then tried a 180 main, and it didn't help at all. 180 seems a little rich IMO. I'll try the "tape the intake more and more and see if that changes anything" trick. I'll also set my needle richer.
Bryan, I'm not sure what idle jet it's got right now, just the one that came with it. I'll check
