Coasting Richer System

The coasting richer system is used on 1975 models and 1976-77 Federal 1600cc, manual transmission equipped models. System consist of accelerator pedal switch, vehicle speed switch, and carburetor modifications. During coasting or deceleration, throttle valve in carburetor is closed, creating a leaner air/fuel mixture. To prevent misfire and high combustion temperatures, the coasting richer system injects fuel through coasting richer jet, reducing oxides of nitrogen (NOx) and hydrocarbon (HC) emissions.
