      Hello everyone,

      I am in need of the diagrams for a Evinrude Zephyr model 4378 circa 1945. I contacted mumbles but all he had was the ones for the 4404 so the carb was a little different. Mine doesn’t have a primer on it.

      Also when i was disassembling the carb I managed to brake the small tube that is labelled as the "air bleed" (Part #275251) in the diagram I do have. Is the tube all that important or can I just run it with the plug with just the hole in it instead of the tube?

      Thank you all in advance,
      Ryan

        I think you need that tube to supply idle air when the carburetor is set to slow.
        You can probably get a new piece of tubing at a hobby shop. Take the old piece with you to the store.

          Hi Wyo307 (Ryan)
          I have a copy of the Operating Instructions (includes parts section with diagrams) for the Evinrude Zephyr Models 4378-4379,
          which I would be very happy to scan and forward to you. If it is OK with you, I would need your email address.

          Time is a bit of a problem at present with the Christmas Season keeping me well occupied, but if can give me a few days I would be delighted to help you out.

          Kind regards

          MonteNZ
