I have an 88' 70hp johnson that has a regular fuel pump. At idle it sounds like it is starving for gas and when I try to accelerate it is very slow and never really gets wound up. If I hit the choke with it is running it will smooth up for a couple of seconds until it begins to flood. I have checked and replaced fuel lines but I believe that it is the diaphram in the fuel pump. Does anyone have any other suggestions to try before throwing parts at it?<br />Thanks<br />Chieff
