Ok just trying to get the new 300 setup and I was going through the carb. Right now I've got: 165 main 35 Pilot I don't know what the needle is due to the fact that the prior owner tightend the retainer cap/nut so tight that I can't get it off. I'm guessing it's the stock needle it looks to be in position 1. Right now I'm thinking it's running really rich. I'm at 4800' and it's in the upper 30's, so I'd guess this is rich? Now I've got a few jets laying around and I'm guessing a jet is a jet, just different bores? So I've got a 160 as well as a 162S, that S thing has me puzzled and I'm wondering which one I should run?
