Probable cause

A failure of the left magneto grounding lead resulting in a 'hot magneto' condition.

Analysis

During engine start, the pilot observed the starter operating, but not engaging the engine. He turned off the magnetos and battery and exited the airplane to investigate the problem. He did not chock or secure the airplane. He turned the propeller some, then began to walk away. The engine then 'roared to life.' The airplane proceeded across the ramp and collided with a parked Beech 77. An inspection of the airplane revealed that the left mag would not ground out with the switch, resulting in a 'hot mag' condition.
