The invention is directed to an arrangement for assisting an operator to adjust a carburetor. The arrangement has a display for the setting of the carburetor of an internal combustion engine such as a two-stroke engine. An actual signal proportional to the carburetor setting is compared to desired limit values by means of a comparator and the display is switched in dependence upon the comparison result by a control unit into different operating states. The display assumes a first operating state below a minimum desired limit value and, between the minimum and maximum desired values, the display is switched into a second operating state. The arrangement for carburetor adjustment makes it possible for the operator to recognize whether the actual signal is above or below the window determined by the desired limit values. This is achieved in that, above the maximum desired limit value, the display is switched into a third operating state, for example, by driving the display intermittently.
