About 10 years ago whilst visiting my uncle he asked if i would like the twin SU's he had fitted to his 850 mini back in the late 60's/ early 70's? Of course said i (expecting a set of cooper twin 1 1/4's) and he came out with these    I was having a sort out of boxes in the new lock-up and found them again and thought it was about time i found out what they where. Any idea who made them and what they where originally for? Cheers Craig |

Definitely SU.
I think they are H2's rather than the later and more normal HS2.

I think your right that they are H2's (def not HS2's) and as such pre-date most (if not all) mini's so i am wondering what car they where originally aimed for

Might be H1s, which are 1 1/8 flavour, as fitted to Frogeye Sprites.

AUC738 carb comes from an early Minor Van.
They're actually H1 carbs so 1 1/8" not the more common 1 1/4"
They look like mirror image ones though so does the other carb have a different number?
Excellent looking set up and definitely aftermarket I'd have said. The manifold flange looks like a 1 1/2" SU one. Could be interested in your selling (for what I don't know!)

Follow your dreams or you might as well be a vegetable. |

I'll have a look at the weekend to see if the other carb has a tag (I don't remember there being one). the carbs are a mirrored pair and only 1 of the carbs has a choke lever on it. I would consider selling them,, but i too don't know what they are worth  |

I am wondering if thet where fitted to the A series powered series 1 lotus 7's in the Lotus Seven "America" spec?? Can't find any pic's, only a description  Compression ratio 8.9:1. For the US market ("America" model), Austin Healey Sprite (Mk. 1 Frog-eye) with twin SU H1 carburettors on special manifold developing 43bhp at 5,200rpm. |

Can't be from an A series - that has a two port head and there wouldn't be space for two of these assemblies (one for each port) - and 4 carbs would be nonsense.
But maybe the manifold in your photo would bolt onto a standard single carb manifold, ie two carbs into one manifold then another manifold then the head. But that wouldn't make much sense either...
I think it must be from a single port engine, or maybe a V or flat. Beetles have something like this don't they?
Or...
maybe they were fitted to a supercharged engine, ie two carbs into one manifold into (single port) supercharger into inlet manifold. That's more likely.
Superchargers weren't uncommon pre-war, so are they from something like a 30's MG?

Dunno, I think that they are most likely a bolt on conversion for single carb'd engine as the separate manifolds would have been hard to get hold off and expensive. Anyway, those going to the autojumble tomorrow can have a butchers at them (or even buy them ) |

I owned an Austin 7 special a few years ago and they look like something from 1950's that was fitted to such.
"At the end of the day" I wouldn't be surprised if they were a cheap and cheerful twin carb set up for an 850 Mini - as they were originally fitted !

Id say they are meant for the willment overhead valve conversion on ford prefects ... they used to convert them from sidevalve to ohv and fit twin su carbs

Paul H The thing that makes me think its not for an A series is that the carbs would have been from a bug eye sprite, so you would have thought you'd have fitted the inlet and linkages as well? But something for a 50's special is what seems to sit right in my head. |
