set its factory setting first,
HSN 3-4 turns out
LSN about 5 turns out

and set your HSN first until you don't get any booging sounds again (do it very carefull byt turning the screw very2x slowly about 1/8 turn coz buggy's engine is very sensistive).
If you finished the first step, then set your LSN.
get it to full throttle and let it go off throtlle for about 5 seconds. if the engine stall after that then your LSN need to be leaned a little. if the engine sound raise then your LSN is too lean. after that you could set your idle RPM with you idle screw.

it's simplest method that i use and work okay with me.
i recomend you to get temp measurement tools since it's really important for buggy's driver.
BTW, id you don't have it. drop some wter to the head and if they evaporate about 1-2 second then your engine is running hot but remember that every engine has different gottest point.

good luck
