A display system for an engine includes a processor configured to receive a first measurement indication relating to a measurement of a fuel control valve position of the engine, wherein the fuel control valve position is configured to control an air/fuel ratio of the engine. The processor is further configured to compare the first measurement indication to a first preset fuel control valve range, generate a first completion indication based on when the measurement is within the first preset fuel control valve range, and display the first completion indication on a display of the display system.
