Sunstar 380BL, could anyone help me with threading this machine

Make sure you're going counterclockwise around the thread tensioner. (one of the drawings in the manual makes it look like you go clockwise)

One thing that the manual does not show but that is actually important is that the thread needs to go between the tension discs, not around them.

The other thing I would change is I would skip going around the post (see attached photo with arrow) that prevents the tension discs from spinning. (Unless you're looking for ways to increase the maximum amount of tension you can get.)

If you'd like to send a photo showing how you've got yours threaded, we can let you know if it looks right. The components are quite similar across LOTS of machines.

Also, is it making good stitches?

 

friquant. Like a frequent, piquant flyer.
