      I’ve been given a distressed 1952 Evinrude 3 hp Light Twin. High speed needle valve is scored. New one very pricey. Can I dress it in some way as to be serviceable?

        Sure can, or just post a wanted ad for a good used one in the webvertize. I likely have a few, I can look.

          The seat is probably wallered out too which can make it impossible to adjust. Mumbles showed me a trick using an end mill to resurface the seat by taking a few thousandths off of the face of it to square it up a bit. It seemed to help quite a bit 🙂 .

          For the needle, I chuck it in a drill and use a file to take it down to where the groove is gone while keeping the taper angle the same.
