HSN is the long tube. 3 turns out
LSN is the one on the carb boot 4.5 turns out ~
make sure when closing the LSN all the way in you open the carb fully otherwise it will damage the needle
MSN is the one opposite to the carb boot - next to the HSN
MSN should be flush and take off the HSN, the hole should be facing outwards.
Idles screw is below the HSN (adjusts the "closed" position of the carb - should be set to about 1mm)
