Abstract
Air drawn into a carburetor main fuel passage for adjustment of the air-fuel ratio of an engine air-fuel mixture is either stepwise or continuously prevented from being undesirably increased with increases in the engine load by either closing an additional passage for the air at an engine load above a predetermined value or continuously reducing the effective cross sectional area of a variable orifice in a passage or an additional passage for the air with increases in the engine load.
