Abstract
An air inlet control system for a carburetor of an internal combustion engine. The system includes a magnet, an air inlet valve, and a temperature controlled limiter. The magnet is used to automatically attract the air inlet valve towards a fully closed position. The temperature controlled limiter limits the range of movement of the air inlet valve based upon the temperature of the engine. The limiter limits the open position of the valve to a position less than fully open when the engine is cold and, limits the closed position of the valve to a position less than fully closed when the engine is hot.
