Why it wouldn't stitch

Those of us who love to sew and who know about sewing machines understand the importance of the needle.  I am always amazed that people who complain that their machine doesn't work  haven't changed the needles since "I don't know.." when. 

I think that this needle came from a newer machine that Betsy and I were struggling to time.  I wish that the happy ending was that all it took was a new needle.  Not so.    We gave up and decided  that we just had to use it as a parts machine.  So far, it has given me two tension discs.  And a bobbin case.  So there.  Worth the ten bucks we gave for the machine.
