We were all in your shoes at one time. Just hang in here and you'll get this. What they (the previous posts) are trying to get across to you is that the early IH diesels were both a gasoline and diesel engine in one. There wasn't a second engine, the right side of the engine had all the gasoline components, carb, distributor, etc. while the left side had the diesel components, filters, injector pump, etc. The engine was started using the gasoline side and after a warm up period the same engine was switched over to diesel fuel and the gasoline supply was shut off. Since the engine had warmed sufficiently, and when the lubrication oil and cooling fluid was warm and circulating the diesel could start running. This is all in the same engine using two different fuel types and the components to run the engine in either mode. The problem being it would not start first on diesel fuel due to the lack of development of the necessary components for a diesel as we know them today. What someone else mentioned in their post it is amazing that these 1940 - 1950 era tractors will still be running when today's diesels are out of the picture. Not a bad design with what was available to the engineers in that era. Hope this helps.
