carburization

I would like to know who could help me, I have a problem with the carburetor of my Peugeot 405 BL Model 92 which annulled about two hoses that apparently are from the engine's vent and I do not know how to put it back to work since I do not meet a diagram of how they are connected ..... thank you very much to who can help me

Your problem is anyway in the tuning

Thank you very much attentive

If everything in order of the carburetor and I do not touch more than to remove it .. and put it .. I would not worry about that .. if it works normally .. open and close as it should .. Look that you do not have a sucking air .. and if I would not leave the carburetor aside and I would be thrown more for valve light ... more than anything if it is to CNG ..

Hello, thanks for your answer.
Look now to do so much, I manage to go gas, but if I stop it no longer turns on gas. It could be valve light; He has a hydraulic botler, and up to half an hour before changing the retain he worked very well. I'm going to try thank you very much.
