Anyone's input for tuning the weber carb?

I have a 1989 wrangler 4.2l and I can't figure this carb out. I also can't change it out because of California smog. Does anyone have good knowledge about this carb and how to tune it?

A fuel pressure regulator is a great place to start with a Weber, Mine runs great at 3lbs of fuel pressure.
Jeeps are like bras, the more you put into them the better they look.

I'm ain't real smart, but I can lift heavy things.
