Machine has been soaked in kerosene, every thing loose and moveable. when I spin the balance wheel, the upper shaft doesnt move, The lower shaft moves only when I disconnect it from the upper shaft. There is a washer in the balance wheel, but it will not make the upper gear shaft move, and so the needle will not go up and down either. Is there something missing in the balance wheel, I can wind bobbins, just fine but when I tighten the tightening s***w in the balance wheel and spin it nothing moves. Is there a problemwith the pitch fork looking part attached to the upper gear shaft. The machine is in a treadle and operates with a belt no motor. I have sewed on this machine 35 yrs ago.
