  • Challenger carb settings

    Hi all,
    having problems with the jetting on my MX5 challenger, have looked at amal carb sites, they all have different opinions. So what main jet/pilot, and which slide do i use on concentric 930 / 2

    Start with 300 main , needle net 106 needle on middle clip and a 35 pilot
    Then play from there. Oh and cutaway 3 on slide I think isstandard

      Carb settings

      Hi,
      thanks for the info, at least its a starting point, the bikes in question, were bought from US as derelict desert racers, so the carb settings were not standard, so thanks again i can get on with the tuneing.
