Positive Camber Impossible?

Great info guys. Still unsure if i am able to get my steering to return. I believe this means positive Caster (not camber as I mistakenly posted originally). So how can I get positive Caster? Is it possible? I have now replaced everything, and still the steering is loose. and no return after a turn. I want it to force its way back to the center, and keep that line until I steer. Possible? I am running 14in tires.
