I just purchased a 1991 9.9 Gamefisher motor that will only run with the fuel line removed after the bowl has been filled with fuel. As soon as I put the line back on, when the bowl is running empty, the motor stalls out and it's flooded. I have taken the carb off and cleaned it and the float seems fine. I need help, my son wants to go fishing this weekend. |

I would always start with the obvious (not being cheeky ) but is the wee needle valve still there ? and is it still in contact with the float so that it can shut fuel supply off at correct height |

The needle valve is there. I replaced it when I cleaned the carb. I purchased a factor manual which is not much help with this issue. I am stumped. It appears that the lower cylinder floods more than the top if that helps. |

can you turn carb up and blow into fuel line , you should not be able to as the weight of the float should seal the needle valve , another thing is to make sure float is not puntured, put it in a bowl of petrol and check for air bubbles (keep it held under fuel level )after a while skake float and see if fuel has entered |

If it passes the "blow" test, you may have a hole in the fuel pump diaphragm. That would put enough fuel in the engine to kill it. |
