      Wondering if anyone knows if it matters which direction you wind the secondary winding. I have 3500 ohms for each plug and it had good spark and ran good for 5 minutes, stopped it because port cylinder was getting a little to warm. I let it cool down and tried to restart it and had no spark. Coil still tested at 3500 ohms. I put a condenser in that came out of a Pal and i had spark agian, ran it about 2 minutes and shut it off. I tried to start and had no spark.
      Its like its draining the condenser. I did send the flywheel to a magneto guy that recharged magnets, and when i got it back magnets where strong changed polarity. The magnet closest to keyway was north now it is the south pole.
      Of course it is opposed firing not alternet.

      Thanks Tim

        Changed polarity should not matter. Old condensers can fail quickly. I suggest a new replacement condenser,
