forgot about the warm air diverter, which is run through the valve in the air cleaner on the vacuum lines. you have to have that plugged with the air cleaner off. when it's all warmed up to operating temp, adjust the mixture screw a little at a time, giving time to catch up (3-10sec) until it idles highest, then should be like 1/8th turn lean after that setting. the idle might become too high, so adjust till you get the mixture right, and idle low enough, then do the slight lean adjustment.
