Narrative:

The aircraft had been towed from the overnight hangar to the commuter gate and left unchocked. I failed to set the parking brake. The ground power cart was positioned in front of the left engine. During start of the right engine my attention was focused on the right engine RPM and temperature gauge. The engine came close to a hurry start, so I had no chance to glance outside. After the engine stabilized, I looked outside and thought that the power cart was rolling backward. By the time I realized I was rolling I could not stop short of the power cart. The left propeller contacted the power cart right after I pressed on the brakes. The left propeller was not turning, there was no damage to the power cart, and there was no engine damage.
