I recently got a '96 Honda 5hp 4 stroke that was sitting in a shed for the past couple of years. The previous owner said that before it was stored he had the carb replaced, I do not know why. Anyway, when I took it out on the water for the first time, it started on the second pull, sounded pretty good, but then abruptly died after about 2 minutes of running. After which, it would not start again for a while/a number of pulls, which made me believe that it was being flooded with gas, but each tiem I was able to get it to start it died after less than 2 minutes. Any ideas on what I should try? I am not particularly knowledgeable on 4stroke outboards, so it could be something simple that I am missing. Or it could be that the replaced carb is somehow faulty.
