I have a 1996 3.0 LX Mercruiser Alpha One Gen II. I removed the carburator, took it apart and cleaned all of the rust and gook that was inside it. I put it back on and when I started the motor it started like new and then shut off and wouldn't start again. I took the carburator cover and the flame arrester off and when I went to start it the carburator shot gasoline up out of the carburator. Can someone help me please?
