Morris Minor Owners Club

In my parts hoard I have an old SU carb of unknown origin. It is a sidedraught with a 1 1/8 bore plus vertical inlet manifold flange and a horizontal air inlet flange. Marks on it are. 3457, C6, 1217e. There is no sign of the more usual AU marking.

Does anyone know what it is for please?

Minor MM?

sidevalve series MM with the support for the air silencer .
Could have done with one of those years ago as my car had no silencer went onto ebay bid on one but the guy selling it had listed the support separately so won the silencer but out-bid on support and had to fabricate my own support

I tried the website http://sucarb.co.uk and a search brings up 'FZX 1217' as being "HS6 Carburettor for a Austin Princess 1800 'Automatic' 1976-79".

I'm sure that's probably not the one.
Perhaps if you want to have a play on there it might throw up something else?

Thanks gents, I had already searched on line before posting here but without conclusive result. SU do not seem to have been very consistent with marking model numbers on their carbs. The MM appears most likely. The 803 also had a 1 1/8 carb but that was semi downdraught as on all the ohv engines.

If it is MM it is presumably also suitable for a Morris Eight although there seem to have been some changes on the Eight over the years.

Are there any markings on component parts, like the needle or float, that might help isolate it to a particular era or generation of Carb?

Post-1948 UK spec Series MM, by the looks of it. Early cars had float bowl on other side. Steel intake is for the silencer rather than the export filter.
