My 740 with a 34 34 solex Z11 Carburettor will not idle prop
 

Hello my 740 I brought from a older man who sadly passed away. I'm having trouble with the vacuum hoses not quite sure there in the proper place it hasn't got a egv thing i don't think. It idles very rubbish and if I rev it up it just dies which is bad because it's a automatic. There isn't much information on the Internet on this carburetor so could I ask some help please.
