Hi everyone, I've replaced my primer bulb twice already but thats not the prob. It keeps losing prime on my small carburated outboard. Lines and connections are good. It only happens after I sit for about 5 minutes, once it runs, it goes great. I believe that means that the leak would be on the engine side? Could it be the needle& seat or the connections to the motor?
Any advise would be appreciated

Take the cowl off of your motor and prime the bulb, look for leaks around the carb, connections, and fuel filter.

Mine was leaking at the line, where it was clamped to the tank barb. Just because you think your lines are good, doesn't mean they (or the connections) are.

i just had to take my line apart, cut fresh ends and put back together, it was leaking at the connections around the primer. all is good with the rest so i trimmed it up and re sealed
