I have one and she runs well. Did you take out the bobbin and reset it? Is the needle properly in place? Does the machine sit flat in the table? I honestly can't think why it would make a clanking sound. I am still in the learning stage and am often reminded of what it was like to learn to drive a stick-shift. Hope you get an answer soon.
Edit: I just realized that there are built-in diagnostics. Have you checked them all?
