摘要： An improved carburetor is provided wherein a bidirectional passage is provided between an air velocity reader and a location downstream of a throttle. Metered fuel flows into the bidirectional passage adjacent the air velocity reader. Flow direction in the bidirectional passage is dependent on the pressure relationship between the ends of the bidirectional passage.
