      Nice work Dave, it all starting to come together.

      I posted a picture on this post  of an A-35 Motor I originally bought for parts. Pulled the flywheel

      last night and the coil tested positive!

      Running into a snag with the plugs wires that are held secure by the bakelite screw in collars & bushings.

      The bakelite collars backed out easily but the bushing have a firm grip on the plug wires that prevent me pulling the wires out, plug wires will push forward but not pull back.

      At this point it appears I may have to remove the coil, cut the plugs wire off short and push what remains forward threw the bushing.

      Tubs, as I recall you’re familiar with this scenario, any and all feedback appreciated.

        I think I would pull the coil anyway, just to clean out
        the old tar potting and clean the contact on the coil.
        Some of those had glass insulator
        tubes around the coil secondary terminal, that often
        are broken.

        Here’s a magneto from my A-45 that I pulled all apart.
        I can’t remember if this one originally had glass insulators
        or not, but after I attached the new plug wires, I packed
        some “fish”? (insulating paper used on generators, etc.)
        paper around the secondary connections.

          I follow Buck’s suggestion and remove all the tar
          when I’m changing the wires. If you don’t feel
          comfortable removing the coil to avoid having to
          re-aligning the shoes, you should be able to clean
          things up leaving it in there
          This picture is from an A-25. You probably missed
          the springs and glass tubes. You have to be very
          careful as they are easily lost it the clutter. You
          likely never know they were there if weren’t told
          to look for them.
          Try some petroleum solvent like carb cleaner, kerosene,
          engine de greaser, exct. to dissolve the tar and free
          things up. Heat gun will also help.
          When you get things cleaned up a little check to see if
          the wires could be soldered on.

            Sure, removing the coil  & cleaning up is the way to go.

            I was asking more from the thought or question is the only way to change the wires is to remove the coil. I see no other way without forcing or damaging the sleeve/insulator/bushing.

            On another “A” mag I left heels in place and just removed the coil so realigning was not a problem.

            From what I’ve seen on the early “A’s ” Johnson used a variety of schemes at the coil/plug wire interface, interesting stuff. Makes me wonder if Finn was behind all this !!

              Question answered.

              With sufficient lubrication to loosen the plug wire from the bushing the plugs wires can be pulled “out” without having to remove the coil.

              I did however remove the coil and push the plug wires forward. I did find bushings at the end of both plugs wires making for a snug fit.

              Coil tested live again with readings across both primary & secondary windings.

              My memory is not so good at times. To remove the coil I did have to remove the heels as well.

                Thanks! Tubs!

                For the pic of the coil and the springs!

                  I finally got the original tank to a condition that I am happy with to paraphrase Tubs.
                  Got the decals on and put it back together.

                    You seem to favor the early Johnson’s. The A-35
                    is a great addition. Won’t be long before you’ll
                    have it pushing your boat. Not sure how much
                    fishing you’ll get in. About the only time I don’t
                    have a motor running is when I need to put
                    more gas in it.
