CEL needle on middle clip, 50 pilot, 172 main, mild port, 19cc domes, +4 timing ridden in glamis, seems like this is lean compared to some specs Ive read here. but , it feels pretty rich up top, I threw a 170 in it , but have'nt rode it yet, gonna check it at the dunes. just wondering why i'm at a 170 and everyone else seems to be around a 180?
