1980 350 Vacuum Line Routing Diagram

Hello-

I recently bought a 1980 Chevy 350 motorhome. It ran fine and just passed smog, until I started tinkering around.

I replaced the fuel and air filters which meant removing the air cleaner housing. I noticed upon reassembly that two vacuum lines were loose. It appears that the aluminum nipples pressed into the carb for vaccum pulled out. I found the proper holes in the carb and put the lines back to what I thought was correct... Now the motor will start but runs horribly and will die after a minute of idling. It now smokes (whitish gray) out of both exhausts and I also noticed a lingering amount of emmisions staying in the exhaust tips not being expelled.

I have a repair manual, but it does not contain any vacuum line diagrams. Does anyone know of a resource of such a diagram?

Thank you in advance!!!!!!
