In the early days, some of the UK tuning firms offered twin H1 carburettors, i.e. 1 1/8".
According to the Mk1 Performance conversion website they were pretty good.
Quote:
...these carbs proved to be a real go faster goody. As with the similar Downton units they were originally designed for fitment to the small bore Austin Healey Sprites but proved just as successful on the smallest of all Minis. There are a few Minis still in circulation that are using this type of carb, either in conjunction with a larger 295 type cylinder head or offset rockers. My personal preference is for the rockers as using the 295 head can cause flat spots due to the comparatively large size of the inlet valves compared to the ports and venturi of the carb. Retaining the original 623, 850 cylinder head is also more "in keeping with the original specification.
I have set off a frogeye, and the matching Alexander manifold that I plan to put on my Traveller, eventually.
