Stephen,
If you can feel any lip on the bore of the king pin, you should remove
it. The fulcrum pin needs to fit snuggly, with good contact all around
the bore. If there's lip that holds the fulcrum pin away from the
surface, the joint may loosen over time.
You can remove a little material on the flat tapered section of the
cotter pin with a file. You don't want to change the angle of the
taper, just make the cotter pin thinner. The pin will then go in
farther. Just take a little bit off at a time and test fit it. Repeat.
It's easier to remove material than to put it back on. :)
