1. A display system for an engine, comprising a processor configured to:
- receive a first data measurement indicative of a position of a fuel control valve that controls an air/fuel ratio of the engine;
compare the first data measurement to a first fuel control valve range, wherein the first fuel control valve range corresponds to a target air/fuel ratio while the engine operates at a low engine speed, a low engine load, or both;
generate an indication of an adjustment to be made via a regulator based on the position of the fuel control valve and the first fuel control valve range;
display a first completion indication related to completion of the adjustment made via the regulator;
receive a second data measurement indicative of the position of the fuel control valve;
compare the second data measurement to a second fuel control valve range, wherein the second fuel control valve range corresponds to a target air/fuel ratio while the engine is operating at a high engine speed higher than the low engine speed, a high engine load higher than the low engine load, or both;
generate an indication of an adjustment to be made to a carburetor based on the position of the fuel control valve and the second fuel control valve range; and
display a second completion indication related to completion of the adjustment made via the carburetor on the display.

Abstract
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.

12. A fuel system, comprising:
-
a fuel control valve configured to control an air/fuel ratio of an engine; a regulator comprising a regulator adjusting control configured to adjust the fuel control valve; a fuel flow restriction control configured to adjust the fuel control valve; and a display system, comprising a processor configured to; receive a first data measurement indicative of a position of the fuel control valve that controls an air/fuel ratio of the engine; compare the first data measurement indication to a first fuel control valve range, wherein the first fuel control valve range corresponds to a target air/fuel ratio while the engine operates at a low engine speed, a low engine load, or both; generate an indication of an adjustment to be made via the regulator adjusting control based on the position of the fuel control valve and the first fuel control valve range; display a first completion indication related to completion of the adjustment via the regulator adjusting control on a display of the display system; receive a second data measurement indicative of the position of the fuel control valve; compare the second data measurement to a second fuel control valve range, wherein the second fuel control valve range corresponds to a target air/fuel ratio while the engine is operating at a high engine speed higher than the low engine speed, a high engine load higher than the low engine load, or both; generate an indication of an adjustment to be made to the fuel flow restriction control based on the position of the fuel control valve and the second fuel control valve range; and display a second completion indication related to completion of the adjustment made via the carburetor on the display. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
