I’m,concerned you think the low speed adjustment is in fact the high speed adjustment. The knob on the top of the carb is high speed adjustment, and yes, it should be opened 1 1/2 turns to start a cold engine. Once running and warm, I’ll bet it smooths out at about 3/4 turn. The low speed needle is on the underside of the carb and should normally be about 1/2 turns open.
Engines will die from not enough fuel and too much fuel!
