I have a door in a downstairs bathroom in a 40 year old 4 level split.

The problem I have is that the door won't stay open. After you open
it, it always swings closed about 4-6" - which is not much, but since
it is a small bathroom, it is just enough to jam the door into your
hip as you turn around.

What can I do with the pins or hinges to make the door stay in the
fully open position?

How come your subject says "Door Won't Stay Fully Closed" but your
body-text says "the door won't stay open"?

In any case...

Some suggest bending a hinge pin to introduce friction.

Some suggest shimming a hinge to balance/plumb the door.

Few suggest checking the wall/jamb for plumb and fixing it if
possible.

One (glenn) suggests "An elegant solution is to replace one of the
hinge pins with a shoulder bolt the same diameter and use a nut on the
other side and with proper torque, you can squeeze the loops together
just enough to keep the door in one place. Cheap solution is to use a
machine bolt instead."
