Mine was spring over small pin, small pin through hole in cam, push small pin up with small phillips screwdriver and insert decompression shaft through end of cam.

I already told you. You put the spring in then the pin and then slide the rod in the cam while your pushing on the pin thru the bigger hole on the back side of the cam.
If it's together right the pin should come out when you turn the rod and retact when you release the rod as long as you don't rotate the rod to far off of the flat spot for the pin.
