What does this do ?
Hanging on the side of my ex Sierra Pinto carb. There seem to be two air pipes and an electrical connector.
I can't find it in Mr Haynes.
What does it do ? Is it necessary? What are the electrical connections ?
 
carb thingy
I'm addicted to brake fluid, but I can stop anytime.

Is it actually part of or attached to the carb in some way?
Difficult to see in the photo, but it looks like it's not part of the carb, but just hung there because it's convenient?
Does the fuel line run through it?

No it's just hanging there.
Don't think there is fuel, just vacuum.

It's probably an electrically operated vacuum valve used to switch things in the carb (normally one end the inlet manifold (i.e. vacuum feed)
and the other to a diaphragm actuator on the carbs, for say deceleration emission regulations....
Keep meaning to remove mine on the CVH as the actuator in this case stops the throttle completely closing to reduce VOC emissions snag is in a light
weight car it goes into "self drive" mode, as there is to much open throttle!!

What engine/carb is it?
1.6 Emax maybe?
Obvious questions where do the wires go and what happens if you disconnect them?

I think you'll find it's an anti run on valve . When you switch ignition off it opens an extra vacuum inlet to the carb thus making the
mixture too weak to run on - Fords (& others) had big problems with engines running on in those days, an extreme example I watched keep going for
nearly 2 minutes (we were timing it!) until we finally gave up & stalled it!
I no longer run Furore Products or Furore Cars Ltd, but would still highly recommend them for Acewell dashes, projector headlights, dominator
headlights, indicators, mirrors etc, best prices in the UK! Take a look at http://www.furoreproducts.co.uk/ or find more parts on Ebay, user names
furoreltd & furoreproducts, discounts available for LCB users.
Don't forget Stainless Steel Braided brake hoses, made to your exact requirements in any of around 16 colours.

Had one on a 1972 Capri Cologne 2.6, it's a valve that opens on deceleration to weaken the mixture, anti polution device, took it off after
warrenty, no ill effects.

Russ, I think you've got it
But thanks to everybody for the suggestions, particularly the flux capacitor .
