yamaha 9.9 4 stroke 1995

Hello, The diaphragm for the accelerator pump was leaking so I changed it out for a new one. Now the motor starts fairly easily and idles but starts to flood as soon as I crank up the accelerator. I cannot find a problem in the carb. Everything is spotless and the float and needle and seat appear to be working properly. Saw a thread on a google search with someone with the exact same problem but unfortunately it was never answered.
Any help or ideas appreciated.
Thanks, Russell
