Hello Scott,
Make sure you are threading the machine with the presser foot up so the thread goes between the discs, top tension 4 or 5 and you should be able to pull the bobbin thread through with slight resistence, if it is too tight slacken the screw on the bobbin case about a quarter of a turn anti clockwise and test and adjust until you get it right.
