getting to much fuel

i'm working on my friends 1980 6000 and its flooding out pretty bad. I pulled carbs off inspected them and cleaned them all looked well. got it running good again then after sitting all night go to start it today and its trying to start but won't, pull the plugs and theyre soaked. My guess is the fuel pumps diaphram went out so i pulled the vacuum line off and didnt see fuel but i still think that is the problem. Don't know what else would cause this, the floats are not sticking either and neetle and seat are fine too. any feedback?

If it flooded both cylinders, then it's a carb problem.
If it was only the one cylinder then it's likely that the fuel pump is leaking.

When you had the carbs out, did you test that the needle valves are sealing properly?
