And he said to give that bobbin screw a quarter turn. Usually a 16th of an inch turn one way or the other will do wonders. If the bobbin just plain unwinds when you hold onto the thread, tighten the screw (turn it to the right) just a little and test again. If the bobbin won't unwind at all when you jerk it, it's too tight. Loosen it by turning that screw to the left just little (lefty loosey) and test again.
I've done this many times and it is easy. Just don't be scared of your bobbin.
