Some have no adjustments, those that do are: ......initial adustments for both high(H) and Low(L) needles are:
1 1/2 turns "out" from a lightly closed needle.
This is just the intial adjustment. Once it's started it may need futher adjusments for proper performance.
What makes you think it needs adjusting?
