Machine is set up for narrow hemming. Right needle. But it won't sew.

White speedy lock 1600 - was sewing perfectly then the right needle broke I replaced it and rethreaded the needle and it would not loop the threads together - I rethreaded the machine with the same results - I replace the left needle and rethreaded the machine again with same results. I cannot figure why it is not looping the threads together.
