I can remain silent no more, carbs take a beating on these jeep sites because most people know very little about them. A carb can be worked to actually out perform fuel injection! Granted you would have the cost of a fuel injection set up in the carb, but you would also have a lot more tune ability with the carb without having a lot of expensive electronics, that water and mud can affect. Carbs don't require map, coolant,cps, along with the mile of wiring that goes with injection. Carbs don't require 13 volts to keep the pump running at the 40 psi pressure most injection uses (a carb can be gravity fed to get home) you say a carb won't run off camber? I have a 55 model Cj that will almost lay on it side and never miss a beat ( it does have a floating oil pickup so don't try this without one) has mileage you say? My yj with 3.07 gears 4.7 stroker, gets 22 - 24 mpg! So please don't be so hasty to con-dim a carb! Now for the original question, no I wouldn't take fuel injection off something that already has it because its gonna be expensive to change it over to carb! That is to better what you have now! You will need a top of the line carb for starters, then you will need a new distributor with mechanical advance, new fuel pump, fuel pressure regulator , intake manifold , new throttle linkage, the list goes on and on! Instead if you want to get away from the Chrysler computer telling you what you can and can't do, why not go to a mega squirt computer, then you can have the best of both worlds with full adjustability!
So thanks for letting me rant, I know some wont agree with my logic, but I have been in this business for 40+ years now, I build and tune carbs as well as fuel injection systems, both have their good and both have their bad, it's just a matter of what you want it to do!
