Hi Tim
These carbies were STD on the MGA as twins, i ran 3 of these on my FJ Holden along with every body else.
These carbs were used on all types of race cars back in the fifties/ sixtys, i ran a set of these on my
997 cooper in the late sixties.
These carburettors are the ones they have to use on the historic minis in the UK appendix K very much sort after.

Thanks Graham, it's good to hear that they were used over here too in various competition cars. I haven't seen many minis here using them today, I guess HS4 is a more reliable option but I've really come to like the look of the H4 on UK cars
These are the genuine special tuning pair which have most of the parts still there

The post I’ve been waiting for. I run a 1310 with a mild cam and the car has M needles fitted. I’ve been very ill so my memory is a touch hazy, but I did call GR I think but can not remember what he recommended but I do remember him advising against M’s. What needles are people running in twin HS4’s? I would rather just buy one set than multiple, at stage I also have an AEM AFR gauge ready to have the Lambda bung welded in.
These are H4 carbs, which are a little bit different to HS4 but take the same needles. This spec of H4 were recommended to take CP4 needles, which is the same as the needles in the Australian police spec Cooper S with twin HS4
