    I found that a good starting point is to set both high and low screws at 1 turn out. aka. remove plastic caps (red and white usually), turn screws clockwise until they lightly "seat" then back out (counterclockwise) 1 turn. This is usually a good starting point. Also I like to leave them alittle rich for the fact a saw runs different once under load and temp is usually colder outside.

    A saw with alot of use or lower compression will usually need @1.5-2 turn out on the low speed due to the fact the engine can't develop the low pressure or "sucking" force through the carb at low speed as well as a fresh/new saw.

    you really need to learn to tune by sound and you will know what back off meens. If tuning with tack or by turns of the screw your right.
