i second this. OS works even if your setting is bad. Anyway, heres my break in process maybe this could help you...
run 3 tanks on engine hanged no throttle (must be on the neutral setting)
set the full throttle opening to only 25% and run 5 tanks around the track
set the full throttle opening to only 50% and run another 5 tanks around the track
set the full throttle opening to 100% and run 3-5 tanks
after this you can start adjusting the high speed needle to lean. Be careful in setting too.
