I was happily driving in the freeway when suddenly the car started loosing power and stall. I turned of the freeway to take the backroads home. Found that I could either creep on litte gas or give full gas - anything between and it started to stall. When I opened the hood back home I heard a "hissing" noise from the carb when the car was idling - looked at the carb - saw some holes I have never seen before (see picture) and true enough it was sucking air through one of those holes, the others are threaded and there is also a piece of gasket left - So I'm pretty sure a piece of the carb is missing/dropped... (genious) But WTF is it??

Hey - I found it - it was resting under the engine
I wonder if the screws are there as well...

Yep! Found the screws as well on the shelf under the engine - what a fantastic car! _________________ Praise the lowered! |

super
looks like the accelerator pump to me!
when you floor it, the butterfly opens and gives the engine a gobfull of air, which leans out the mixture until the revs pick up and start to burn the air supplied, so to compensate this little gadget pumps a squirt of fuel into the venturi when you floor it!!
when Chavs are sat pumping the throttle, revving their corsa's for all they're worth, it's this little pump that's making their life worthwhile,
but don't tell them _________________ if it aint broke, fix it till it is |

You never know what you need until you miss it (Isn't there a saying like that...?) - and I needed that little accelerator pump. _________________ Praise the lowered! |

Sorry folks,
but that is not the accelerator pump, it's what we in the UK refer to as the 'choke pull-off device' and is designed to open the choke flap slightly as soon as the engine starts, to prevent the mixture being too rich.
The older models of the 26/35 carburettor had a simpler and better arrangement, with a strong spring in the mechanism which partially opened the strangler as soon as the choke knob was released.
These later devices are not very well designed, as many of them fell off ( ) and the majority of those which stayed in place are ineffective since the vacuum diaphragm has failed.
Test it by trying to pull the little wire rod forwards when the engine is running. If there is no resistance, it's just a useless ornament, not to mention being a source of an air leak into the manifold.
Some advice below about how to proceed when getting rid of the thing.
