the machine appears to be working, I have checked thread tension in both places, when i run the machine without fabric in place (and without thread in the needle) the feet seem to be moving as they should. but once i add fabric to the mix, i get a ball of thread in one spot till the whole thing jams and stops. I am familar with this machine but was not the last to use it. it is threaded correctly and the needle is the correct one. I'm stumped ! please help if you can!
