Thread: Old Holley 2 bbl ID and info wanted

    Default Old Holley 2 bbl ID and info wanted

    Hello, Just bought an old model 2280 2 bbl carb, I have googled my eyes dry to find more details about it
    R-8051
    0758



    I think it's from 1978, but not sure.
    Think it's rated to around 250 cfm?

    Any ideas from which car it comes from?

    Help is very much appreciated, thanks in advance!

    Oh... yes I believe some linkage is missing and one adjusting screw...

    Arrived today, and it doesn't say Holley on it...any known copies of the 2280?



    Air filter is just a tad smaller than 7" and on the wing nut it says "Japan" (Trans-Dapt 2292?)
    Also, the choke pull off has number 1326 on it.
    Top piece with choke: 1R 1859 B (no ventilation in the bowl above the float bowl)
    Middle part with float and throttle butterflies: 6R-5563B "Made in Japan" (one power jet plugged)
    Float: 510 HOLLEY and A51
    Base plate: 12R-7833B
    What I think are the main jets have number 279

    Does the jet number indicate that it comes from a smaller engine?
    What number is the smallest jet?


    I live in Sweden/Europe

    It has the same throttle lever

    Yes, thanks!

    Do you know if jet size 279 is one of the smallest sizes?
    I've found a source for the Hygrade rebuild kit here in Sweden, hope that's a good kit?

    I have a "Holley Illustrated Parts & Specs Manual" at work.
    I'll see if it has any information pertaining to your carburetor.

    The Hygrade carburetor kits are made by Standard Motor Products and are very good quality.

    Wow! Thanks!
    Even the throttle plates have number 259 as the illustrations show
    As far as I can tell, the carb looks to be in good shape, so I will definitely rebuild it.
    Found it on Swedish Ebay and won the auction with about 37 USD. Seller thought it was a Weber...
