Gas Guzzling SOB

Boy's Imma Bout to trade her off for a 4 banger of some sort. I've replaced the air filter,plugs,plug wire's,did a nutter bypass, set the fuel/idle mixture screws in till she barely runs and she's still drinking the gas like a college coed at a frat party,I'm talkin 8-10 mpg.I love my jeep but damn the cost of gas these days it's becoming a burdon just to ride.It's either trading it off or swapping from the carter carb to a weber,mc2150,or holley.This is the first jeep I have ever owned,so Im asking from the more experienced jeep owner's what do youns recommend?

if your looking for better mpg stay away from weber, I was getting about 8 with mine. it was about 4 years old and needed a rebuild but the mpg was only about 12 when new. I switched to a holley 4bbl. and offenhauser manifold and now get 15-16 in town.

Some people report that a faulty o2 sensor is to blame for their poor mileage...

I noticed in your avatar and gallery pics that you are running larger than stock tires. Have you recalibrated your speedo to reflect the change? It could make a difference depending on how you measure your mileage.
