Sean,
are you refering to the low speed needle. Also, If you can not find any info regarding how many turns out you need to go, start out with 4 complete turns. Then use the pinch line test and see where you are from there. before you do the pinch line test clear your motor out with 3 or 4 full throttle blips. Make certian your high speed needle is not set to lean. that will be a good begining point of reference. I suggest you do this only if you can not find factory settings..
