Start the carburetor at 1 turn on the high and 2.5 on the low. Don't idle the carburetor, and I mean to keep the butterfly closed and keep the engine running by burping the throttle. The carburetor will be able to tune without dead spots or hesitation at this point and you have less cylinder wash caused by the fuel. The butterfly will basically catch the fuel when off the throttle in the corners and release it when you go back on the throttle acting like a faux accelerator pump. This is all in the link to the pdf but if you need more help let me know.
