The pilot reported that he hand propped the engine because the electric starter would not start the engine. He instructed his passenger, seated in the right seat, in the use of the "T" handle brake system, which had to be pushed in for the Johnson brake bar to work. The pilot then set the throttle between one-quarter and three-eights of an inch. Once the engine started, the pilot observed that the engine produced high power and the aircraft began to move forward. The aircraft knocked down the pilot as it accelerated across the airport. The aircraft crossed the runway and a taxiway and collided with a fence and trees in a park to the west side of the airport. The pilot reported that he did not understand how the brake could have been released. No tie-downs or wheel chocks were used.
Probable Cause: The pilot's failure to tie down the aircraft prior to hand propping the engine. Factors were a fence, trees, and the pilot's inadequate preflight planning/preparation.
