      Dumb question here.  Will one coil fire two plugs?

        NO, these Tecumseh coils are “single” secondary.
        This being an alternate firing motor, that’s a good thing.

        I only had one coil on the mag plate during the test…….
        just wanted to see if the Tecumseh coil would work.
        Have to locate a set of points for the other coil before
        I can forge ahead.

          More progress? on the magneto today.
          I found the missing half of the point set,
          and repaired the broken spring metal spring
          on the other half.
          For now, I’m going with a good original coil
          for one cylinder, and the Tecumseh coil
          for the other.
          I’ve never did a swap with “mix and match”
          types of coils…….. not sure if there’s any
          negative consequences in doing so.

            That non-matching coil experiment will be interesting.As long as they both spark their plug,it doesn’t seem like it should matter.
