(ENGINE ADJUSTMENT)

1、每台发动机出厂时都经过了初步调整，用户可以直接使用。但各地区的海拔高度

将会影响化油器的正常工作，化油器油针可能需要进行微调才能达到最佳的工作位置。

Every engine has been adjusted to average mixture settings which will most likely allow

the engine to start and run in most locations. However, as altitudes and barometric

pressures vary by location, it is very likely that the carburetor mixture settings will need

to be adjusted to obtain optimum performance.

2、功能及调整（Functions and Adjustments）

（1）、风门，冷启动时使用(Choke Lever)

（2）、油门(Throttle Lever)

（3）、怠速调节螺丝(Idle Speed Adjustment Screw)

（4）、低速油针(Low Speed Mixture Adjustment Screw)

（5）、高速油针(High Speed Mixture Adjustment Screw)

调整：顺时针转动怠速螺丝3将增大怠速转速，同时要配合低速油针4一起调整，顺

时针转动低速油针减少油量（一般是把油针拧到底再退回1圈）；高速油针5(退回1圈)最好

使用转速表来调整，使发动机达到最高转速，加减速顺畅为最佳。

ADJUSTMENT: A general starting point is 1 turns out for the low speed needle (See No.

ADJUSTMENT:

4), and 1 turns out for the high speed needle (See No. 5).

Adjust the High needle to peak rpm. If ever the engine slows or dies while at full throttle,

the high speed mixture is likely too lean.

Adjust the Low needle until you achieve a smooth idle and a reliable transition to high

throttle. If the engine dies when the throttle is advanced, the mixture is likely too lean. If

the engine stumbles when the throttle is advanced, the mixture is likely too rich.
