With a different carb and no "nutter" your engine is prolly running waaaay retarded! With the 32's on there I'm surprised it don't run hot.
The carb you took off was controlled by the computer in your jeep...just as the dist still is.. The carb and dist make up the control the computer has on the smog. So now all the computer has is the dist..and it retards the timing trying to get the smog correct.. and it cannot without the factory carb.
So when changing the carb one MUST do the nutter bypass to make the engine run correctly.
Together with the tall tires no doubt you are wanting for more horsepower. Do the nutter and check the gearing to see what is in that ride..should be 3:07 from the factory.
If 3:07 put some 4:11's in there and you will be happy for a long time.
Then when you get ready to do a huge upgrade to that jeep...just trade it for a rubicon and you will be a lot happier.
