Thank you sandy girl....... My machine comes without a pedal...I did take it finally yestreday to a qualified repair shop and they were so wonderful.....they worked on it 6 hours yesterday...yes 6 hours while I was standing and waiting.....the machine had at least 3 problems that they had fixed and they did exchange the bobbin case ( the black upper part ).... ..... Lets hope it won,t cause problems anymore...... I know things like this happens I only hate when it happens to me...... Thanks to all of you..... One more thing, they recomend me to use another stabilizer ( cut in stabilizer ).......
