I was just wondering if a 89 jeep 4.0 can be changed to a carb setup and get rid of all the computer stuff,injectors etc, or is it just a pain to do this.

 

I have no idea, but, the first non sponsored link when googled brings me to Morris 4x4, I've never used em, so once again, no first hand experience. But, they sell a carb and just below that, in the accessories section, an adaptor...
Idk, do some searching on here and google. Chances are there's a good write up already in existence. Good luck.

 

Carb is only half the problem, no? Isn't the ignition also controlled by the ECU?

Assuming you can get a properly-sized carb that fits, change the fuel pump to a low-pressure device and find a breaker-point or stand-alone electronic ignition...I don't see why you couldn't remove the electronics.

 

Well..........you could try a 2bbl set up off a AMC Eagle of the similar vintage. They were carbed

 

You can do it msd and a webber done
