3cyl 4000 cab pump rebuild questions

Inside this cav pump Im rebuilding for the learning experience. Ive seen videos talk about the snap ring inside the housing. Mine looks out of place compared to some of the videos Ive watched. Does that matter?

Then on the fuel plate I was wondering if I could adjust it to add more fuel. Or if this is the correct setting.

Full disclosure this pump worked fine but leaked like a screen door on a submarine before I took it apart. Who knows what it will do when Im finished.
 
The snap ring is not set for timing on Ford applications like MF/Perkins and Cummins did. The max fuel setting can only be correctly verified on the test bench.
