I take it English is not your native language as that is really hard to understand...?
Anyway..

Air leak from one of the pipes to the carb (carb to AEI unit usually or D/V leaking)
Carb base not sealing, may need a small smear of sealant between the gasket & the inlet manifold.
Idle jet may need a clean.
Mixture (Co2 adjustment) screw may have snapped off in the carb base, a new screw will sort this..
Poss air leak from green seals on spindle of butterfly.
Are you sure you replaced all the gaskets correctly with the right ones ?

I am Portuguese, therefore Ingles half deficient that I write.
The pipes of vacuum to AEI are good, I only changed the old gaskets for a new kit, and relanti was sufficiently steady and the screw of mixture left to make effect, squeeze and relief and it do not make nothing, have manometer AFR and the mixture in relanti you the always poor one, before when opening the screw of the mixture was very soon rich and now it does not make nothing, is poor always.

hi if its not a big job for you its better you open again the carb from top and check if the jets are all cleaned very well cause this is the problem that renault 5 gt turbo carb do when you change the gasket,what i mean is you need tochange everything once you opend it

Mixture screw is for idleing only... look in to getting smaller jets in your carb..

Yes possibly it's snapped off & not adjusting at all, does the mix screw do anything at all when you turn it in or out ?
