The thread loops under the fa?
The top thread on my Frister and Rossmann Fantasy 972 loops no matter what I do. Adjusted the top and bottom threads makes no difference. I noticed the top thread catches between the bobbin case and a nearby metal component, making a loud clicking sound which is probably caused by the bobbin case being the bobbin case being pulled out of its housing before the thread frees itself.
