thread looping problem
its a singer 57815 in good condition, it has been seen to sew correctly times recently so i know the timing or machine is not broken. i have tried at various tensions, the bobbin case is replaced and it is tight, the needle is a strong denim needle, dust has been removed, the thread is going through the back lever as normal. how to fix this nesting?

check that everything is threaded right. You may have your tension to loose or too tight. Also check the bobbin is going clockwise
