I have a Singer 338 that I love, but I have a small issue with the foot pedal. It is one of those older two button pedals, and it is very stiff, which makes it hard to control the speed of the machine. Basically, it's either pedal to the metal fast, or it doesn't really go at all. I took the pedal apart to see if I could loosen it up a little, but it didn't help.
So I want to get a replacement. Do I just get a pedal and rewire the existing cord to the new pedal or can I just get a whole new pedal for my machine? I took a pic of the end of the cord where it attaches to my machine, and the cord has four prong holes, but the machine only uses the bottom three.
