My 1965 Fordson Super Dexta, basically the same thing as a Massey 135, has been sitting for three years. The last time I used it, it started half running as if on 2 cylinders. I have crunk it since by pulling it off, but it runs like a gallop. I rebuilt the injector pump, retimed it twice, so I think this is not the problem. I expect something with the valves or a hole in one piston? Trying to get the head off today doing exploratory surgery.... I can't get the head off. All bolts are removed. Any tricks? Scared to hit it to hard. I have attempted to use a chisel, using the wedge shape to lift, trying to drive it into those areas that have excess metal, beyond the head gasket, but this is not working.
