IMPORTANT: The plugs have to be out when you work the crank. JasonG's post above does have you do it that way but I want to point it out specifically. If you rotate a cylinder that will try to compress air, when it's got liquid in it, you can bend the crank or damage valves. Because you can't compress a liquid, and something has to give.
Also, depending on how much you wiggle the crank, you might have some kerosene come out at you. BTDT.
