    Apparently there are different distance between mounting holes / bolts centres,
    of old to new carbies, but it does not stop carbies being swapped.
    read all the fine print from the Service Bulletins as found here:

    Brett,
    I do not know for sure but I have some NOS Amal 398 carburettors and spares (for Ransomes MG crawlers) which I believe are based on the same arrangement as the 397 but with a horizontal rather than vertical mounting flange.
    There should be a spring on the choke lever which should prevent the problems of the choke self closing.

    from spending a bit more time looking at pictures of carbies and the manifolds, i am confused about you statement of the carby attachment / inlet bolts being vertical, all i can find are horizontal mounts.

    can you please post a few pictures here of your actual machine so we see the physical setup?

    there is at least one with parts not to be found in any Howard parts manual,
    see pic from Howard Register.

    cheers Rod.
