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.

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.
