Claims

[Scope of utility model registration request]

In an engine equipped with a carburetor having a cam breaker that detects the engine temperature and releases the fast idle cam when the engine temperature exceeds a predetermined value, the cam breaker's operating actuator and the engine temperature signal are activated. 1. An engine idle control device, characterized in that a delay device is provided between a drive mechanism that drives the actuator and a delay device that delays the actuation timing of the actuator relative to the actuation timing of the drive mechanism.
