Carb leaking and water too

[steplift20]

I ha ve a 1984 50 hp Mercury o.b my top carb is pissing out fuel from the port side of the front bowl I know it has to be rebuilt but I noticed that water drips very slowly ffrom my top spark plug where it seats to the block, when I race the motor the gas does not leak only at slow speeds and the water I don't know the engine seems to run great when the idle is high I don't like the water drips from the top plug any help would be greatly appreciated Thanks
