I just bought a Worlds S7 two days ago,and let me tell you(great craftsmanship!) Just a question I really could not make heads or tails of the breakin instructions. Is the carb preset for breakin? And if not what do you recommend? I am glad to join the team,here at R&B and hope to hit the track soon.

Break in the engine using the carb as it comes. The only thing you will need to fiddle with is the idle or airspeed screw. Adjust it till it will hold a steady idle. It will sound like a 4 stroke since it is so rich.
