I want to thank each and everyone one of you wonderful members!! I have the Singer Futura Emborider sewing machine and after all the suggestions and tips, I found that it is indeed a wick and it is very oily! Funny finding that in a sewing machine. I did get the wick back in that tiny hole as so many members suggested I try to do. It seems to be sewing OK, but I still have that thumping sound so I will try the other tips on changing the needle. After that I just might take it in for a professional cleaning and ajusting.
Thanks again so much guys! I knew I could get my answers from you. You all are the greatest!
