I seem to remember that the owner's manual calls for about half an oilcan of engine oil to be squirted through the two lids in the valve covers. There are felts in there that soak up the oil and let it drip slowly over the rocker bearings and over the rockers to the valves. This oil runs into the crankcase, so should be the same as the engine oil. I used to oil our engine in the morning and before starting up again in the afternoon, but with not so much oil. I always assumed that a lot of oil would just drip out and maybe not be available later in the day. Strange that such a great engine would have an extremely primitive valve-oiling system. The lower end, with the huge ball bearings, is a masterpiece of engineering (for its day, anyhow). I always thought the engine ran really smoothly for its size, and that there was just a little extra power because of the lack of friction in the ball bearings. By the way, the tall pipes sticking out of the valve cover are primers, and were supposed to be used if the engine was stopped on kerosene and could not be started again. I suppose they could be used in the morning too, but I never had any trouble starting our 10-20 (which always used gas) with the choke only.

He wanted to get the rest of his corn in by the next day (Christmas Eve). We had about an inch of new snow on the ground and single digit temperatures. So in the bac
