Hello Terry,
Go through these things first which might sound obvious but try it anyway, When you thread the machine make sure the presser foot is up so the thread goes between the tension discs, top tension between 4 and 6, bottom tension should be enough to pull the thread through with some resistence, make sure the needle is in the correct way round, you should be able to adjust the bobbin tension by turning the larger screw about half a turn at a time clockwise to tighten, if you are still breaking needles and can't get the stitching correct you will need to retime the machine.
