Cessna 182 partial engine failure forced landing KBKS Falfurrias, TX 10 23 12

Routine pleasure flight cut extremely short. Fortunately for me, 200agl ruled out a turn attempt although I had the natural urge to try for a split second. FAA still working on cause. Possible ignition or induction system. Site examination ruled out bad fuel, mags, separated engine components. Everything under cowling was intact. Typical pilot error components confirmed not an issue with the video. Checked primer locked once stopped, so also nonissue. Happy to be alive.
