The airplane sat idle for a two months prior to the accident. The pilot reported the battery had enough power to rotate the propeller through only one rotation when he attempted to start the engine. He exited the airplane to turn the propeller in an attempt to '...get the engine at the top of its compression stroke.' The pilot reported he turned off the master switch, but failed to turn off the ignition switch prior to moving the propeller. He moved the propeller one-half of a turn and the engine started.
