OK, I think I understand what you are saying. You can only turn the low speed needle 3/4 of a turn. This is because their is a stop on the plastic knob that keeps it from turning more than that. That stop is easily overcome by simply pulling the plastic knob off the low speed needle and resetting it in a different position.
You can also defeat the stop on the plastic knob by not pushing the knob completely onto the needle, then turning it.
Yes, I would start with an initial setting of 1.5 turns out from gently seated. You can loosen the packing nut slightly to make it easier to turn the needle. Retighten/snug the packing nut once the initial setting has been set/confirmed.
