getting a sewing machine serviced

It needs to be higher! If it's looping at the back, that means that your bobbin thread is tighter than your upper thread, hence you need to tighten the upper tension - loops at the front would mean the opposite. Try it at about 4/5, then go higher still if the loops are getting smaller.

Thanks I will play around with it. I had to turn it down when I was using a twin needle as it was too tight.

Sometimes mine does that when the bobbin thread isn't running smoothly, so I would check that. I also find that sometimes the tension dial gets "overwound" so wonder about pulling it out / taking it off, cleaning it, and starting again - maybe marking the dial yourself (I had a machine once that stopped conforming to the "official" tension guide)
This is just very general advice - I am sure you won't do anything you are unhappy with!
