    Hello all,

    I wanted to introduce myself. My name is Hugh, and I recently acquired a 1965 CJ5, a 30,000 mile original. Parade Blue, blue seats, white top, a real beauty, and a ton of fun! I bought it out of Michigan where it spent 53 years at a hunting camp. It came with all the maintenance records as well as most of the parts that were replaced along the way, such as points, caps, and even the original windshield wipers! I'm enjoying getting to know it and I'm sure I'll have questions along the way. Here are a couple:

    1) The radiator has a slight leak coming from the bottom of the core. Radiator shops don't seem to be as common as they once were. What would you do--re-core the original or buy a new one? I'm inclined to restore the original but I'm curious about the reliability of radiator repairs (I realize it also depends upon the shop).

    2) It starts and runs great but hiccups upon tip-in of the accelerator, from a stop and when changing gears. Is that a specific symptom of one aspect of the carb or a sign a general carb rebuild is in order? Curious to know how these carbs behave.

    I've always had British sports cars (I presently have two Austin Healeys) and understand British car peculiarities (and there are plenty), but the Jeep is new territory. Thanks in advance for any advice.

    Re-Core your original radiator, much better material than todays replacement.

    And Welcome

    Welcome from Oklahoma! That's a beautiful jeep, I am glad it is going to be cared for.

    There are a few radiator repair shops around here. If you find any around your area you might call them to see if they work on old school radiators. One of our local shops has one of their elderly semi-retired guys come in once or twice a week to work on brass radiators. He can rod them out or re-core them as required. You might find someone like that.

    1) Radiator - I always prefer to repair and keep an original radiator. Far better quality. No need to re-core if it can be cleaned, or 'rodded" and/or any holes soldered/patched. I doubt a modern core would be anywhere near as durable as an early OEM.

    2) Carb - what carb, what engine?

    3) British cars - ...my sympathies to you. :D

    Gorgeous Jeep! You are lucky to have such a nice, unmolested example.

    What have you checked so far on the engine? I would start with the basics and give the Jeep a tune-up: timing, dwell, plug gap, re-set idle mix etc before blaming the carburetor.

    Even if it cost quite a bit, trying to get the old radiator repaired is probably the best plan...they are dying out, but I've been able to find a couple radiator shops that will rod-out as well as re-core an repair an old brass and copper radiator. Just for comparison, if you wanted to buy a new, OEM style replacement using traditional brass and copper construction:

    Welcome from Michigan, Hugh. I found an old Radiator shop that re-cord my stock radiator, now gone, they are had to find anymore. I would suggest keeping the Carte carb, but be carful where you source the re-build parts, I got a kit that was all junk, wound up only using the gaskets, and the accelerator pump, all the rest of the parts didn't help, made it worse. I used all the factory parts after cleaning them well. I also had a few English experiences, with Motorcycles and Cars, Good Luck. Rick

    If the issue continues after you work through the recommendations in post #7, you are probably looking at an accelerator pump issue with the carb.

    Tune up to OEM/FSM specs is the first step, otherwise you'll be chasing your tail.

    Welcome from France. I have a 4 cylinder, your Jeep looks fine but this is the body.
    You can clean parts inside.
    My carburetor was full or dirty things, (accelerator pump). With the help of the forum, I cleaned all parts and since now 2 years it works perfectly.
    I change small parts time after time, when I find them with the explanations provided here.
    There are many solutions for radiators, according to pro shops around your place.
    Just be careful, ask here before.
    If you have problems with direction, the" tightsteer" thing makes miracle, with Ross gear box.
    Good luck with your Jeep, and enjoy.

    Thanks for all the replies. Good point on the basic tuning--I'll go through that first. I'll report back on this once I have time to go through it.
