ABSTRACT:
An idling system for a multi-cylinder two-stroke engine as used in an outboard motor. Through a porting arrangement in the carburetor of at least one of the cylinders, the fuel supplied to that cylinder at idle and off-idle speed is reduced to a value so that the fuel-air ratio is too lean to fire. On rapid acceleration from idle speed, a charge of fuel is injected directly to the non-firing cylinder to provide smooth acceleration.
