Narrative:

Returning from ZZZ1 for lunch, the engine started running rough, so I decided to land in a desert dry wash to check out the engine roughness. On rollout from landing, one tire got in very soft sand and the plane nosed up and both propeller blades contacted the sand. I decided to walk out and get another propeller. The engine roughness was caused by the right magneto 'P' lead shielding contacting the 'P' lead and shorting out the right magneto. Returned with svcable propeller, corrected the magneto shielding problem and flew the plane to trm. No damage.

Narrative: RETURNING FROM ZZZ1 FOR LUNCH, THE ENG STARTED RUNNING ROUGH, SO I DECIDED TO LAND IN A DESERT DRY WASH TO CHK OUT THE ENG ROUGHNESS. ON ROLLOUT FROM LNDG, ONE TIRE GOT IN VERY SOFT SAND AND THE PLANE NOSED UP AND BOTH PROP BLADES CONTACTED THE SAND. I DECIDED TO WALK OUT AND GET ANOTHER PROP. THE ENG ROUGHNESS WAS CAUSED BY THE R MAGNETO 'P' LEAD SHIELDING CONTACTING THE 'P' LEAD AND SHORTING OUT THE R MAGNETO.
