All variants of the Kafer car considered in this manual are equipped with a carburetor of the same type, in which, depending on engine power, the diameter of the diffuser and the set of jets are different.
Each carburetor was tested before installation at the factory and adjusted for a specific brand of gasoline. This adjustment must not be changed independently Excessive fuel consumption and reduced engine power almost always have other causes, among which the driving style and driving conditions are the main ones. Usually you can limit yourself to carefully adjusting the idle speed. Their correct adjustment is more important than it is commonly thought, since it affects the increase in engine response even to achieve medium speeds.
The operation of the engine after turning off the ignition and stopping during heavy braking is most often the result of a re-enriched idling combustible mixture; Exhaust knock in a moving vehicle, on the other hand, indicates a lean mixture. Decreased throttle response when depressing the accelerator pedal is often attributed to either too little or too much fuel from the accelerator pump.
