Vacuum/Carb Help

I have been having some issues with the carb on a jeep that I have owned for a few months. It is running rich and seams to only run well if I pump the accelerator. Someone said that it may be a vacuum problem, so i want to start there and get some advice and opinion on the current setup.

I have been reading these two articles to try to educate myself.

In this first picture the part that is labeled "A" does not look right to me. I am wondering if it may be leaking.

What is the part that is labeled "B" in this second picture it is located at the base of the distributer.

I am running the non-vacuum fuel pump

Here is an over view of the whole system.

What do you think? If it needs work where would you sugest getting the parts?

Your description could mean almost anything. First of all, a vacuum problem is normally a vacuum leak which makes the engine run lean. Rich can be caused by a dirty air filter, engine needing a tune-up, carb float out of adjustment or weak carb needle valve, fuel/air mix idle screw out of adjustment, vehicle timing off... etc. You might want to start simpler with a tune up and fresh plugs, and then work your way up. Find a repair book and get dirty. You pic labeled "A" looks strange but not like a leak unless that little rubber cap is torn.
