Anyone know how to time a k3b mitsubishi engine? Is it shimmed and where could I get the right shims? This is in a Massey Ferguson 1120 tractor. When I bought this tractor I was told it needed an injection pump. It barely ran pouring black smoke when it was loaded in my truck. Since, I have not been able to get it to run.Supposedly the engine had been gone through, but it all seems suspect to me. Where can I get parts reasonably priced? I may need a rebuilt injection pump, injectors and probably glo-plugs, maybe a gasket set. Thanks for any help.
