Narrative:

After landing and turning off the runway at cmh, the right engine stopped. As I attempted to restart it, it was obvious that it caught fire as a look out the right side windows showed a bright red glow. I immediately shut down both engines, called for a fire truck, turned the master switch off, and exited the aircraft. The fire was out by the time I was out of the airplane. Possible causes are a fuel system/mixture failure or over-primed condition from the attempted restart.
