Some times it helps to turn the machine in a direction that you haven't had it setting in and let gravity be your friend. You will have to pull it out of the cabinet - well I guess you could turn the cabinet on it's side or back........ I had a Singer that was making me crazy. I oiled it and oiled it. Finally I laid it on it's back side and ran it. Some oil must have run in the right place because all of a sudden it ran better and quiet. There are only so many friction points but some how that oil has to reach them.
