Get the fuel pressure down to 2# to 2 1/2# and check float height.

hi not a lot of information, did this problem start all of a sudden, or after you did something? and what did you do ? do you have a original fuel pump or electric ? I am not a fan of the electric. fuel pumps, overflowing with gas can cause a fire, very quickly can cause more problems then they are worth, did you remove the needle and seat , and check if dirty,worn, foreign made parts, or original ? also float could be the problem, sounds to me maybe it is a sticking float from sitting, tapping on the carburetor may clear it up, use plastic hammer, or wood mallet is there dirt in the system ? car sitting for long period of time, ? my 2 cents 37Ragtopman get back to us ,,,,to see how you made out,!

37Ragtopman - Running electric pump, the flooding started all at once, just started car up, ran real rough and would not idle then I noted the leaking carb. I had noticed some slight dampness on the top of the carb a few months ago. Car had not run for several weeks. Does have fuel filter at tank prior to the pump. Not sure about dirt - have not dissembled yet. Thanks for any other help. V8JR

If fuel pressure at carb is indeed 2.5 to 3 psi you should be ok, providing needle and seat clean and good shape and float level is correct. You may just want to lower it a bit.
