If the machine does not feed properly
Instructions from my Universal AZZ manual:
a. The stitch regulator dial is set at '0', make sure the dial is not set at '0' position
b. The feed dog is dropped, raise the drop feed knob
c. The pressure of the presser foot is insufficient, increase the pressure by pushing the head of the darner
It appears that "c" may be your problem. But without seeing a picture of your machine I will again quote my AZZ manual. The pressure regulator knob is called a darner in my manual.
"Depending on the weight of the material a change in the presser foot may be indicated. To reduce the pressure, place index finger on the left hand of the round base of the darner in order to control its rise. At the same time, with the index of your finger of your right hand turn the head of the darner to raise either partly or fully depending on the material and operation".
Keep playing with it Noel. You will get er done!
