I am rebuilding my Jennings and have now got the lights and mechanism working. The mechanism works fine when it's outside the cabinet, but when I install it the handle doesn't work correctly and the machine then jams or just has a loose action to the lever. On removing the base plate I found a piece laying near the pump. It's shaped like a twin fork with a hook end on it. Besides there being loads of loose nuts around the handle, I assume that this piece is the problem. Does anyone have a pic of where it should fit or describe where it goes?
