Am I supposed to cut it in half so that there are two "half moons"? The FSM says to leave about 1mm out past the edge but I am a little confused as to if it is supposed to be cut in half? If it is, why wouldnt they just make the new seal in two pieces?

If you have more than enough rope seal for both halves of the engine then you need to cut it in half.
Get yourself a brand new Stanley knife blade / new knife blade and cut onto a soft surface like a bit of scrap wood. Do your best to make sure the cut is clean and straight - practice for the next cuts!
Lubricate the seal before fitting
Ideally some form of engine assembly lube is best
Whilst holding the rope seal in the middle - position the rope seal in middle of the casting at the locating pin.
Push the seal onto the pin as best you can.
Next with clean hammer handle covered in more lube (engine assembly lube is best! If not engine oil) push the seal more firmly onto the pin.
With the hammer handle you now need to roll from the pin position to one of the outer edges
Then repeat for the other edge.
Rolling action is necessary - do not drag
When you have it fitted so that the seal just sticks out of the recess you then need to cut off the ends as described in the FSM. Take your time with this so you get clean sharp square ends.
I hope this helps.
