I just read the reviews on your model--they are very good. I noted that your presser foot lift has 2 heights....are you letting it down ALL the way? Also, have you dropped the bobbin in with thread going wrong way around? I have an Elna that the thread ABSOLUTELY HAS to! make a little clicking sound when it is seated thru the bobbin "threader" (when you drag the thread thru the slots on bottom).
