featherweight 221
HI, I have a black featherweight machine. It has not been used in quite a while and it's running rough and heavy. I did put a drop of oil in the bobbin case. The booklet says to put oil in two motor grease tubes. I looked at the picture and the machine and I don't know where these tubes are. Could someone give me some tips on how to make the machine run smoother? And ideas of where to oil it? Thanks so much!!! DaleenKay
