I have been going crazy with my carb flooding on my outboard. I put in a new carb kit but to no avail. I replaced a bad bulb in the fuel enrichment circuit. I then found out that there is no atmosphere relief in the carb fuel bowl. When I disconnect the hose from the top of the carb the outboard starts right up and runs smooth. I need to find out how to place a hole in the enrichment bulb to vent the fuel bowl.
