Weber 34ICH vacuum hoses to airbox to where? pics help please.

Hi, Just got my 1.3 back from a certain emporium… and it was  hard to start and running very rough at idle…stalling frequently. I adjusted mixture (as new mot show very low C02) which helped a lot, but then realised  that the two original pipes (to flap for hot/cold air?)  which fixed onto the back of the orange jet unit in the base of the airbox, (there when it went) in-are now missing!.. I have got some second hand hose but do not know which hoses on which side goes to what!
Can anyone post a diagram or photos showing the correct layout for ALL the carb/airbox hoses,  as at the moment nothing is on those stubs. It ran okay before with this carb before.
Thanks.Marcus.
p.s what is the good C02 readout setting for a 1980 1.3?
