Motor floods ( gas)

I have a 70HP Evinrude that floods very easily. It is becoming more and more diffficult not to flood the motor when pushing the key in ( choke). Do I need a carb adjustment?
If I hnad prime the ball,I have no chance of starting the moror for an hour or so.

Put this on the Evinrude page and you will get more responses. There are some good techs over there.
