Hi all I tried to get the
outboard for the dingy going and discovered this problem. It's a 5 hp two stroke Merc. When I connected the external tank to it the
fuel floods the carb. If I try to start the
motor without the tank connected it runs fine, as soon as I connect the tank it floods and dies. This
motor also has an internal tank so I put
fuel in that tank started the motor and switched over to internal tank and the same thing happened. Ok I thought the float be stuck in the open position, took the carb off the motor and cleaned it all out, I even opened the screw that is in the bottom of the bowl and shot carb cleaner inside shook it all up and I could hear the float moving. Thought I was all set, put it all back together and still have the same problem. My question is, could there be a small hole or tear in the rubber diaphram that is mounted on the side of the carb where the fuel line connects, or do you think it is still a float problem. If it is a float problem are there any little
parts that will come flying out when I open up the bowl? I seem to remember this happening when I tried to fix my lawn mower many years ago.
Thanks
