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 preset before ex-factory; it can be used directly by the customers.
However, altitudes will influence the performance of carburetor, to obtain the best output of DEL
engines, slight adjustment at the carburetor is very necessary.

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1.25圈）；高速油针 5(退回1.5
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:
Turn the Idle Adjustment Screw (See No.3) clockwise will increase the
idle speed. At the same time, turn the Low-speed Needle (See No.4) clockwise to reduce the
gas. Normally, the preset from factory is screw down the Needle and then turn back about
1.25 loops. High-speed Needle (See No.5) is turn back about1.5 loops. But we suggest it
should be adjusted with the tachometer to obtain the maximum speed. For the best
performance, engine should be accelerating and decelerating smoothly.

Step 1: Close the Choke and turn on the ignition power supply with full throttle.
(2) 用力转动螺旋桨， （最好用启动棒）直到发动机发出爆炸声.发动机会运转1-2秒而自
动熄火.（首次启动或长时间不用可能需要转动多次螺旋桨）。
Step 2:, Spinning the propeller hardly with a Start-up Stick or hand until explosive sound
is heard. Engine will stop automatically as a result of a rich mixing gas. ( The engine will need
propeller spinning few times for the first start-up or Has not been used for while)
(3) 打开风门，油门开至怠速或比怠速稍大一点,启动发动机，进入正常工作状态。
Step 3: Open the Choke to idle or little higher and start up the engine again referring steps
