Working on a holster this weekend and the presser foot is getting stuck in the 'up' position. I can push on it and it will snap back down, or essentially raise it with the foot pedal and it will fall. Then it will work a little while and then do it again. I've also noticed when raising the presser foot with the pedal, it isn't a 'smooth' cycle, if that makes sense. I keep my machine well oiled, unless I'm missing a port somewhere.
Anyone experience this before?
