With the screwdriver you've just got to be a little careful to get the blade in the pump drive slot and apply enough pressure so it doesn't jump out and nick the distributor drive gear on the cam.
If you're running a can filter with element, be sure to fill it with oil...let the element get completely soaked before you put on the lid. If you neglect to do this before the initial crank you'll bleed off oil pressure while the can fills. Spinning the pump alone will take some time to fill the cannister so filling it manually is going to work to your advantage. Hope this helps.
