115 Merc fuel

[gjsm]

Can anyone explain why my motor is getting to much fuel to all four of the carbs, the motor is running very rough, they were rebuilt and new needles were put in. I have double check the valves, they are correct ones, also seets seem to be in good shape as well.???????

Usually a single carb leaking is a inlet, but with 4 leaking it sounds like human error are the floats and the heights right?
