Which of the following reactions of the moped can you expect, if while starting abruptly, you release the clutch lever without increasing the engine revolutions?

Releasing the clutch too abruptly causes an immediate connection between the engine and the drive wheel. When the engine is operating on low revs, it does not generate sufficient power to overcome the resistance and set the vehicle in motion. Such a sudden, heavy load leads to the engine choking and consequently stalling.
