hi... i use to play with ninja engine... but i cant remember the stock setting... as the manual dun state it. but u can try with 4 turn for the high end (to play safe) and 3 turn for the low end. Then slowly lean the high end to get the power. If urs starts to loss a bit of compression, u can up the idle a bit more... thats what i did to mine too... it might be idle at a higher rpm ( but not too high till it is screaming), which will be better then it cant idle.
