Merlin IIIB / Metroliner engine startup

1981 Merlin IIIB engine startup. There are only 50 left in the United States. Since the engines are Garrett Dash 10s, the startup is a bit different than a King Air, TBM, or others that use the PT6 turboprop engines.
The Merlin IIIB is one of the most capable single-pilot turboprops in the world.
