It is in a Johnson 3004 Tractor. It is three cylinder Diesel. I have seen several different engines f=referenced but not this one. I woula appreciate the help. I need manuals etc for it.
I took some pictures but cannot manage to post them.
I believe you cannot post pictures so long as you are a guest.
Search the engine over very carefully, looking for tags that are riveted to the engine block, intake manifold, or valve cover. Chances are they have been painted over. Also look for stampings on the engine block.
