Cylinder won't fire, has compression and spark?

One of the cylinders isn't firing on my 1950 willies jeep. The spark plug was black and dry, I replaced it thinking it was defective, still didn't work. I checked to make sure it was getting a spark and it was. I checked the compression and it's good but it's still not going. All four cylinders were firing a week ago until the fuel lines got clogged up. After I cleaned everything out, the problem started. The carburetor needs a rebuild and possible isn't sending enough fuel but it's wierd that only one cylinder isn't going. Any ideas?
