I have experienced the same issue at times with leaks around the accelerator pump shaft (and other places too) after doing a rebuild. One thought I had is if the pump plunger doesn't seal well inside the accelerator pump well, it can get past the plunger seal and proceed to slobber out wherever it can. Some of the kits have a leather seal and some have neoprene. If that's the case, the other unwanted result is that you won't get an adequate pump shot of fuel from the accel pump down the carb throat upon hard acceleration. I'm thinking if the carb body itself is worn where the accel pump shaft rides it can contribute to the leak also. You may have other issues with your particular carb, but this is one condition I have encountered.
