I have a Mercruiser 140 with a Mercruiser carb, the carb has just been rebuilt and was working fine for about 20-30 minutes. After that I could hear the engine starting to stutter and when at full throttle it would start to bog down and hesitate worse. Over the next 15-20 minutes it slowly got worse by the time I had almost reached the dock it was down to a bad idle and about 100 ft. from the dock it stalled and wouldn't stay running anymore. I brought the boat home and after a couple hours of sitting I put the muffs on and it started up perfectly and idled fine, also the throttle was once again working without the engine bogging and stalling. The boat wasn't running hot and the fuel filter from the tank is clean as well as the one on the carb. New plugs, coil and points/condenser were also installed within the last couple of weeks. I have tried searching the forms as well as google but have been unable to find someone else that is having this exact issue. Any help would be much appreciated.
