I do have a couple of questions. The top cover has three rivets at the front for a bracket on the underside. I can't see how it attaches to the front of the cylinder. It seems something it missing as all that is holding it is a screw at the rear of the top cover.
Second, this saw is a manual oiler. The oil pump works but the oil is pumps looks like used sump oil. It is very dark. If I ever get it running do you think that new age bar oil would be ok to use? I wonder if the heavy viscosity of bar oil will affect the pump.
