Technical Diaphragm at throttle end uno 1.0 ie

[Chamitri]

Hi Friends.
My car is a uno 1.0 i.e 999cc EFI one.
The place just above, where the accelarator cable fitted to carb; a diaphragm is located. It is just like the vaccume advanced unit. but smaller than that. tube is missing. Also it seems right position of the diaphragm also changed. Could you please guys tell me how this works and how it need to be placed? ( If you are having pictres thats great) and also to where I have to fit the tubing coming out from this unit. What the purpose of having this gadget?

There is another problem when I depress clutch to shift gears the engine getting speed up(not always). Idling speed seems to be OK. Also some times when gears reducing (say 3rd to 2nd ) not enguaing smoothly. Is it a problem. How to over come this?
Thanking you in advance frends. Have a nice day
Cheers
Chamitri

Hi Emm,
Thanks for your valuable Pix. But the one I'm asking is fitted to this unit. it's located just above the accelarator cable fixing point to the above. The shape of the unit is exactly like vaccume advanced unit and smaller than that. I want to know exact location of the unit and to where the air line of it to be fitted. Actually don't know what is the purpose of it.
If you know regarding this please describe me indetail. In the hynes also no details regarding that.
Cheers
