My 4.5 merc has been in storage for about 13 years. Was given to me by a family member about 2 years ago. he stated that he quit using it because it stopped reving under a load. So I got it out the other day and cleaned the bowl on the carb which wasn't very dirty. I also changed the vaccume and fuel lines. It runs fine in neutral but when it is on the boat and you try to give it fuel it will only take about 1/4 throttle then dies. It is not flooding out. Acts like it is starving for fuel. any opinions will be appreciated.
