I don't think it's the foot pedal, as when the sticking occurs, the hand wheel is also sluggish to turn. Here's a picture, of the possible problem area (2), along with some mysterious goop (1). In the (2) area, there's a groove/scratch, which probably shouldn't be there. Can't get into the area, to see the plates on either side. The (2) spot is one to be oiled; the oil doesn't seem to stay on it, at all.
The goop feels like Vaseline. Could that be a build-up of old oil?
