Less than 1 pound trigger pull suggests a sear spring that is wayyy to light. I was messing around with trigger pulls and found that if you mess around and bend the leaf spring (middle prong) back too far you can get full auto by accident. Try bending it forward ever so much.
Im just guessing and sharing what I know causes full auto. My particular case was that the leaf spring wasnt putting enough pressure on the sear which caused the sear to catch on the hammer reliably causing full auto fire.
