'80 4 cyl CJ5 engine issues

Just picked up a '80 CJ5 today. Has some issues with the 4 banger though. Runs rough due to carb and fuel sitting for 5 years and also vac hoses on carb. Might also have a rod knock.

Someone has fooled around with the vac hoses. Does anyone have the schematic for the vac hose routing? I have a lot of hoses going to no where and I am also unable to identify the different manifolds that the hoses go to. I have the name of the different manifolds on the radiator shroud but I don't know which is which on the engine.

If I can get it to run smoothly then I can go next to the knocking issue.

Worse comes to worse does anyone have a used good condition 4 cyl I could by?
