In preparation to qualify for night passenger operations, I taxied out to runway 8 and arrived at the end of the displaced threshold. I then turned the aircraft to align with the centerline of runway 8. I slowly applied throttle and after only a few ft I noticed the aircraft nose dip and instantly the propeller struck the asphalt. I turned off the master switch and the 'P' lead switch and then discovered the 'johnston bar' was disengaged from its 'gear down' bracket.
