I just bought my first harley, it is a 92 fxstc 1340 with a S&S super e shorty carb. The bike is from san antonio texas and Iam in PA the bike is awsome but it is running rich I tried turning the air mixture screw in and the bike stays running i tried putting the enrichner down then the bike shuts off when it does run it is rich and i can put new plugs in and they foul in minnutes if any one has any ideas I would appreceiate it thanks
