factory on the n21r carb is 5 turns out on low speed ( pull slide barrel out , run screw in until it just stops , then backout to desired setting ) , high speed needle 4.25 turns out , idle 1.25 out from just closed .

race settings are usually around 3.75 turns on low speed , 3.5 turns out on high speed , 1turn out from just closed on idle screw .

any Q's just let me know
