1998 40hp Honda

I ran for about an hour saturday with the fuel vent on my tank closed. Eventually we hit a no wake zone and the motor died. I opened the vent and tried to restart but had fuel leaking from the dime sized silver disks on the side of the carburetor. I pulled the plugs and found the one plug was fouled. I swapped in a new plug and pulled the carbs and removed the bowls and made sure the floats werent stuck. It seems better now and doen't leak a bunch of fuel but still has trouble at idle and low speed trolling almost like it is loading up. Should I pull the carbs or just check them to make sure they are syncroed or what? Did the vent being closed cause this? I'm not sure what to do with this motor at this point.

Thanks
