Sociable Carburettor

[PaulSpencer]

I have a couple of questions about the carb on my 1912(?) Sociable. This is a picture of the bottom of it:
   
   
   
   Does anyone know what the lever at the bottom does and how to adjust it?
   
   
   
   I assume the broken (and clamped) cable should lead to the "extra air" lever that I don't have. Does anyone have pictures and a description of how this should be connected? My current plan is just to use a modern choke cable, which will work backwards (in to start, out when running). Any comments?
   
   The pictures aren't showing in the preview. If they are not showing for you, they can be seen at http://www.flickr.com/photos/50174133@N05/.
   
   Thanks

I maybe completely wrong, but your carb looks a lot like an Amal as used on British motorbikes in the '30s through to the '60s
   Your vehicle pre-dates Amal by 15 or 20 years, but Amal is made up of three carb companies, so one of them may be yours.
   
   Hope this is of some help - John.

Thanks John. I have not only discovered that it is a Brown and Barlow, but someone has given me a link off list to information and a handbook. Not that this has helped much given my limited understanding. None of the pictures show the lever at the bottom either, so I suspect this is a modification (although it doesn't look like it). For anyone else interested, the link is http://www.barnstormers.co.nz/?p=147.

Hi Paul
   
   Try contacting John Lyons in New Zealand (John l in December/Jan posts). His Sociable is complete and original, and the carb has the two connections to the top.
   
   Good Luck!
