having just done this for feets, it is a bit fresh in my mind.

mark the distributer in two places to the block.
pop the cap
mark the rotor point.

pull the distributer
mark the slot orienation so you can put that back right.
pull the slot/gear

then spin up with a drill counter clockwise to prime.

then put the gear back and make sure the slot lines up where you marked.
then you can get the distributer back in right.
