Who could help me with my Piaggio X9 125 cc ??

Hello and good evening respectively, now good morning, I changed the carburettor with my Piaggio X9 125 ccm. Now I have the problem to put the hoses on the carburettor right again. Is there a way to get that out exactly? I connected various hoses and it also jumped on. Only on the carburettor directly (right side) is a small hose connection where the engine run, cooling water runs out. I don’t know which small cable needs to be on it. TO BE? I say in advance; THANK YOU, THANK YOU, THANK YOU!!! Greetings from 31535 Neustadt a Rbge. Harry K.
