Narrative:

I started the engine after preflting the plane and smoke and flames began blowing into the cockpit. I exited the plane as fast as possible and called the fire department. The FBO tried a hand-held fire extinguisher to no avail. The plane was totally destroyed in 10 mins. I was planning a pleasure flight within vicinity of airport (less than 50 mi). There were no injuries. There was no damage to taxiway or hangars or any other aircraft.
