Hey man I've been following some of you videos, a while back I was curious about the big boy superlight 200, I think it looks good and the 200cc engine is a solid platform. So first, thanks for sharing it because I couldn't find anything like this anywhere about it. As for the carb settings, here is a great video where the guy takes it apart and puts it back together and explains everything including the settings very simply, it might be worth checking. kzfaq.info/get/bejne/qKmfacd7pt7NZmg.html
