Singer 128 red felt wick?
I am working on a 128 with the vibrating shuttle and it has an empty little hole under the front slide plate. I found info on-line that claims it's for an oil felt wick and should have a tiny hole in the bottom for it to drain. I can't see or feel a hole at all. I stuck a q-tip in there with liquid wrench and nothing ever drained and I still can't find a hole. Should I still make a felt wick and add some oil?
