How to set distributor gl1100ad 83 asplencade

Ive finally got motor almost complete now again, but im lookin at distributor and wondering which way the center faces. (center cam that rotates). I guess the part with the screw in it. eg: piston 1 is up and timing though little crankcase hole is set on F firing mark. Seams i can put the distributor center pointing left or right? how do i set this. a little confused.

Does look like a distributor don't it? There is a pin in the end of the rotor shaft and a slot in the crank shaft that it aligns with, it only goes one way.

Great, thx for that. btw: some call it a (mechanical spark advancer cam) the center part? is that the correct terminology?
