I just got my motor out of the repair shop and took it to the lake the next day. It started and ran okay, but then started having problems with it dying when it was put in gear. It would start but had to choke it to get it to start. The primr bulb on the fuel line would not stay hard. After getting it out of the lake we took the fuel line off of the motor and when you squeezed the bulb there were air bubbles. Am I right in thinking that I have a leak and if I replace this fitting that fastens to the motor it will take care of the problem? The carburetor was repaired while it was in the shop and I bought a new fuel tank, so don't think water in the fuel could be the problem.
