How to adjust the throttle of LaVida 5 million version?

First, start the engine, fully open the choke valve, and then slowly loosen the throttle limit screw to reduce the throttle opening, so as to reduce the engine speed to the lowest stable speed. Adjust the idle speed adjustment screw to increase the engine speed as much as possible. Then slowly loosen the throttle limit screw to reduce the engine speed to the specified minimum stable speed (about 800-900 rpm). This repeated adjustment can adjust the throttle opening to the minimum. When the throttle valve is quickly opened, the speed can be quickly increased, and it is better that the engine does not turn off when the throttle valve is quickly closed. If the above requirements cannot be met, continue to adjust the throttle valve and idle speed adjustment screw to meet the requirements. At this time, the idle speed and carbon monoxide content should meet the specified values. The engine speed is related to the number of times of work done per unit time or the effective power of the engine, that is, the effective power of the engine changes with the speed. Therefore, when explaining the effective power of the engine, it is necessary to indicate its corresponding speed at the same time. The effective power specified on the nameplate of the engine product and its corresponding rotational speed are called calibrated power and calibrated rotational speed respectively. The working condition of the engine at rated power and rated speed is called rated working condition. Rated power is not the maximum power that the engine can emit, but the maximum use limit of effective power based on the purpose of the engine. The rated power value of the same engine is different for different purposes. Effective torque also varies with engine operating conditions. Therefore, the automobile engine takes the maximum torque it can output and its corresponding speed as the index to evaluate the engine power performance.
