Human Factors; Aircraft; Procedure
Engine failure on take off at ZZZ in a CSA SportCruiser. After a successful run-up; my student applied full power for our take off roll and engine indications were green with 5;000 RPM. At about 200 feet AGL; engine RPM decreased from 5;000 to 2;000 with a very rough engine. 2;000 RPM is not sustainable for flight in the SportCruiser. I took flight controls and landed on the remaining runway and taxied back to parking with out incident. At maintenance; it was determined that the connection for the outside air filter for the carburetor and the carburetor itself was loose and became completely detached on take off which lead to the large RPM drop.
Pilot reported loss of engine power on lift off and elected to land on the remaining runway safely.
