Hi!! I need to pick your brain for an oooold problem!!! I have a Viking 200s serger, I have watched your threading video what feels like 100 times, but the machine will. It make a stitch!!! All parts move, but loops are not made ☹️ I am threading upper looper first, then lower, but it just will not work.
