Rotate slowly until the piston pushes the screwdriver up out of the hole, Once you hit TDC the screwdriver will start going back down. That's known as after TDC......
So, then you turn the crank backwards so that you return the piston with screw driver to just before TDC and insert recoil rope in it?
