Been having a problem with my outboard it will not get up to full speed with out the primer pulled out. I posted earlier and got advise to clean my carb. I took it apart and made sure it was clean all the orifices where cleaned and clear when I put it back together. I also took apart the fuel pump and looked at it the diaphragm looked intact, but I am not sure how to tell if its worn out. I took it out and ran it this afternoon same problem, maybe even a little worse. Runs like it is supposed to with the primer pulled out. That makes me wonder about the fuel pump. Could it be that its not getting enough fuel unless its aided by the primer being pulled out? The reason I say that is enough fuel goes through the high speed orifice with the primer being pulled out. It now stalls with the primer pushed in when you try to throttle up. Is there anything else that could cause this?
