Im new at sewing and just got this model singer 758 i was so excited until the bobbin will not spin. I also tried to load it with a already wound bobbin and it wont catch the bobbin thread. im worried i bought a lemon ( my recent craigslist find). I saw all these posts with people using same model and was hoping i was doing something wrong. I followed all the instructions to a T both in the manual.and on here.....PLEASE HELP!!!!!
