1. First, adjust the throttle screw of the carburetor to make the engine speed slightly higher than the normal idle speed.

2. Adjust the throttle screw slightly counterclockwise to reduce the engine speed.

3. Generally, the idle speed is adjusted to 1200 rpm, that is, listening to the exhaust sound is ten times that ordinary people can barely hear every second. Sometimes, after the best adjustment, the concentration of CO is still high. At this time, Paris adjustment method or lean oil adjustment method can be adopted appropriately.
