      I cleaned the carb to an Evinrude Zephyr 4404 and upon testing it out again, I found that the little plunger assembly is not pumping into the primer tank. I took it apart and found the rubber to be hardened and shrunk, not properly contacting the sides of the pump to create suction or pressure. I know that the pump is getting gas into it, but not pumping any gas out. Is there anywhere I can find new rubber parts for the primer pump?

        Ken Hall might have the primer cups. I know he has waterpump impellers for the Zephyr’s.
