Re: mileage?
I just did a 4 day bush run and gas station to gas station is 200 miles
so I get an easy check every trip. It was still 10.9L/100km which is
slightly better than 23 US mpg and I still have that beauty of a
Weber-Carter BBD in there... LOL!
Just amazing what a $20.00 carb kit every 2 years does for them...

Re: mileage?
Ya I'm gonna do that in the spring ...after I replace the timing chain. I'm
not a big fan of trying to drive it home with it backfiring all the time ;p

I had an '81 CJ7 with that same setup a few years back. If I kept it at 55,
I got about 24 or 25 MPG. If I pushed it up to 65, I got about 13 MPG. If
I recall, city mileage was in the high teens.
The real adventure begins when you hop on the Chicago freeway system doing
55 MPH in -any- lane. The only thing saving you is that you're in a 20
year old Jeep and they're in an expensive new car.

Re: mileage?
You don't likely have timing chain issues. In order for it to jump a
tooth, the gears must be destroyed. Those chains are good for the life
of the engine and then some usually. One of my CJ steel sets is now on
it's 3rd engine incarnation with the exact slop as a new on measured in
degrees.
I would be suspecting something electrical like a cracked distributor
cap or even a burnt valve for backfiring.
Have you checked the amount of play in your chain? Stock new they have
about 15 deg of slop.
