At 155 mains, 48 pilots, n68a needle middle clip, still has a slight stumble going into power band, cold weather helped some, and going down on the mains is the only thing that's made it better. I've tried everything from leaning out Tue pilot, needle, going richer on all three at seperate times. I spent like 5 hours today trying to get it dialed. Slightly scared to go to 152 mains. I'll post plug chop pics tomorrow when I'm not on my phone. Any tips would be appreciated
