Thread: Tornado Carb Question

  1. #1

    Default Tornado Carb Question

    Hello all,

    I need to replace the carb on my truck. The throttle lever is rusted stuck and the choke plate is broken. I'm looking around, especially on ebay, and I see plenty of Holley 1920 carbs but they look slightly different and have different R numbers.

    Will any standard 1920 work on our trucks (with a 230 engine) or do I need to be careful when ordering?

    Thanks!

    The Holley 1920 was used on many different vehicles. Specifically, Chrysler Corp. used them on their Slant Six engine. One way to immediately identify a Chrysler application is by the air cleaner attachment. It is a heavy wire that runs across the throat of the carburetor with a stud sticking out of the top for the air cleaner to be "wing nutted" to it. Our carburetors have the same casting with the ability to use that wire. But ours used a clamp. My truck came with a suspect carburetor and it never ran right. Also, the jets were different numbers than what our Jeep used. (another clue)

    Maybe you might want to advertise in the wanted section of this forum. There may be one out there that someone is parting out.

    I poke around in the basement tonight, I believe I have an extra. Would need a rebuild, but should be moving freely

    The civvy ones tend to have the fuel line in at a different point than the mil carb and they almost without exception used a different accelerator pump arm and actuation...I must say that the civvy styles I have seen are all better as they dont use the nylon accel pump arm the mil one does which tends to break over years and years of use and temp changes.

    The only exception to this is the 1920 I saw on a friends 1962 Ford van...I think it was the Falcon van?...anyway it had the 144 cubic inch I6 motor and it had the same 1920 with the same accel pump arm as the mil trucks use. Whether anything else does, no idea.

    Maybe that helps somehow...

    When I got my truck, I was handed the carburetor. I rebuilt it but it never ran well. It stumbled on acceleration. I also noted (later) that the jets were a different number than what was supplied in our Holley 1920 carburetors.

    I wrote down the jet numbers in my TMs. I could look it up if you like (they're out in the garage)

    I got a military used carburetor from a member here and rebuilt that with a vintage military carburetor rebuild kit. No problems with the ~1974 parts. They all worked and it just runs great.

    Just FYI.
