    My older kx 65 was running like an animal but suddenly staring backfiring and no power when throttling up. Idles fine but cannot give it any gas . Any suggestions. What is the correct fuel /oilmix , I have been running 40:1.

    Hey Nuvo, please post in the introduce yourself section so that we can say HI

  4. Sounds Like A Spark Problem to me Or probable your Fly wheel throwing off your timing..
    Usually if she is Back firing Ignition Is usually the culprit.

    hope this helps.
