I'll try the Autolite #216, but it would be good if I knew why the plugs are going bad. Unless I'm mistaken, the Champion H10C are a recommended plug for this engine. The issue with the plugs loosing the arc between the electrodes after very little use is screwy. I'm pretty sure something related to the ignition system must be causing this. Four factory defective plugs in a row is highly unlikely.
