Narrative:

We accepted takeoff at Q3 on runway 12. While in position and cleared for takeoff we discovered we could not use Q3 intersection for takeoff. We taxied forward on the runway and said we were going to exit the runway at the next left, because we were not sure if we were legal to depart from that intersection. While we taxied off the runway we noticed #2 engine instruments readings were not proper. We requested taxi back to the gate and a mechanic saw right away that the start lock on the #2 propeller wasn't disengaged and sent us on our way. No write up was made and no maintenance was done. To prevent both situations from happening again I should make sure which intersection I can depart from. Also if maintenance looks at the aircraft we should have them sign the logbook. Callback conversation with reporter revealed the following information. They had to shut down at the blocks but then they did the company mechanic immediately saw that the #2 propeller was still in flat pitch. He advised them to leave the propellers in reverse longer so the start locks would have time to disengage. Reporter admitted they had not checked the engine RPM as they taxied out.
