Throttle cable became detached at the throttle body; cotter pin was missing from castle nut; Engine RPM was stuck at 1800 RPM. Engine was troubleshot according to the checklist with no improvement. Emergency landing was made at a Private airport. The engine was relatively new at 10 days old - around 20 hours of flight time. I circled the airport before setting up for an emergency landing and shutting down the engine short final. A safe landing was made; nobody was hurt and after being fixed by the mechanic the aircraft was flown back to home base.
A C172 Instructor Pilot experiences a loss of throttle control with the engine at 1;800 RPM. An emergency landing is successfully planned and executed.
