The NTSB's narrative final · quoted from the NTSB record

The pilot reported, prior to starting the engine in preparation for flight, he verified the throttle position and chocked the right main landing gear by using his foot. After the pilot started the engine via hand turning the propeller, the engine immediately went to a high RPM. The pilot attempted to hang onto the airplane in order to regain control and decrease the throttle, however, he was unsuccessful. The unoccupied airplane then struck a parked helicopter and a fuel station kiosk before coming to a stop. The airplane sustained substantial damage to the right wing and fuselage. The pilot reported no preimpact malfunctions or failures with the airplane that would have precluded normal operation..
