I don't have a diagram, but it's pretty easy to describe. Not very many are on the carburetor itself. There are at most two spark ports on a 2 barrel. One will be on the front of the carb, underneath the fuel bowl; I believe it is the driver side. Use that for your vacuum advance on your distributor. You may have one on the passenger side under the choke housing for EGR, but I wouldn't imagine you have it on a '74 truck unless the motor came from a car originally. You may or may not have a large 3/8" port on the back of the carb; that is for your PCV valve. That's it for the carb itself. The rest of the vacuum lines run off the manifold.
