At slow idle when warmed up air gets in the fuel line between pump and carb and the motor stalls. I put a clear line in to see this. At start speed the air goes away and motor runs. If I pump the primer ball on the fuel line it also runs any ideas?

Replace diaphragm in fuel pump -------It may have a wee hole in it.
