So you just run it up to peak and back it off 200 rpm? Does it lean out some as the tank empties out? We have talked about that at the field and some say yes and some say no. I have seen some people run them so lean that they lock up during the race and I don't want that to happen to me. We are all pretty new to this racing thing and none of us know much about the proper way to tune the engine for a race.
