Does any one have this machine.. I have had mine for a number of years and really like it until I hit a pin.s Have had it in for repairs and I thought it was fix because it did sew. But after sewing with it for a while the upper thread would get caught under the bobbin case and lift it and I would brake the needle. Back to the repair shop. tried to explain what was going on so he would have some Idea what to look for. bring it home sew with it for a while same thing. Now does the thread have something to do with it. I'M taking it to a different shop this time explain what is going on and see what happens. i Have a viking VIVa but it is not happy with going over a double seam.
