This video illustrates the timing procedure for the Techsew 2600 sewing machine and similar M-bobbin industrial sewing machines.
This simple process consists of setting the needle bar height 2mm above bottom dead center and then setting the hook position to the center of the needle scarf at ~0.5mm distance. The spacing should be as close as possible without touching the needle scarf itself.
For the curious, I'm using a UNICHE stepless ratchet on the throat plate screws.
