There can't be many carb'd 4 litres out there! I really can't see why you'd want to do that. The MPFI on the 4L is a very reliable setup and cheap to maintain.
Not my first choice either, but engine bay fire and 2 failed used replacement wiring harnesses later (you can't buy a new aftermarket) I'm looking at options plus I know carburetors inside and out.

Can't help much there. Probably the reverse of switching the 4.2 to MPFI using the Mopar kit.
That or building your own setup. At least probably need the intake from a 4.2?
I think I'd be more inclined to determine what is causing your harnesses to burn up and fix that myself.

Hi, I have the 1989 YJ and recently April 2025, had the EFI replaced with a Weber Carb. A few teething problems but she drives and she hasnt done that since Jan 24 after an ECU quit on me, so that's a massive improvement. Needed a special plate built but the mechanic built that and the carb sits where the EFI module sat.

Four SU HS6 carbs would definitely raise eyebrows.
Let us know what happens.

Try looking at Clifford performance. With their intake and carb or carbs if you decide to go with the duel carb setup, you can fashion your own wiring harness from scratch.

Hi, can anyone tell me why my carbed 2.5 runs fine for an hour, steady 56mph speed, then when I drop down a gear or come to a stop, she dies?
