On a more valuable or desirable engine, a pressure oiler such as Pre-Luber could be used to circulate the oil and bring up the pressure before fire-up. We skipped this. With the plugs out and new oil in the pan and cylinders, we first turned the engine by hand to make sure everything was free. This is very important in an engine you've never actually heard run. Then we turned the engine with the starter (which, luckily, worked fine). With no load or cylinder pressure, the starter easily turned the mill. We scribed a mark on the pulley to help count crankshaft rotations.
