Adjusting idling

- 1-1.5mm is the standard setting of factory, adjust the

increased RPM a little bit for easy starting.

- Adjust to fuel and piston. For high neutral, turn

left/unscrew calibrating neutral screw. For slow

neutral, turn right/screw-in the screw.

- Maximum RPM is adjusted with main needle

- At the first drive, run as set. Turning clockwise will

be increasing RPM and turning counter-clockwise

will decreasing RPM. Turning clockwise extremely

will over-heat finally to breakage of inside of engine.

3. Main needle

Adjust the main adjusting screw

Low/middle RPM is adjusted with trimming needle.

For the first drive, try to run as set. Stop driving, and the

neutral tends to stop… finally to stoppage, adjust trimming

needle to continue. Pay attention to balancing for adjusting

both main and trimming needles

Note: When needles are changed, be sure to remember the

original positions, and turn needles by 30 degrees each time.

4. Adjust micro adjusting screw

1. The process of run-in before driving

When you get a new engine, we might remind you that

no matter what kind of engine, it is important to clean

inside of the engine. The engine will be damage if the

dust and scruff get into it.

Secondly, for the run-in process, we adopt traditional

methods. In other words, we carry out the cool run-in

process under the condition of rich gas. However, the

adjustment situation of the needle valve accords with

the situation of leaving factory. Turn down the needle

value until the carburetor is in full speed without stop,

and go on with 5 tanks oil during those process, you

should let the engine stop for a while before carry on

following process.

When going load milling, the curtate range of the needle

valve should not be adjusted excessively, approximately

1/4 round is best under preview work or reaching the

properly middle/low speed. However, the main needle

only need be curtailed a little. We suggest that the

temperature is no more than 90 centidegree .

2. Switch on transmitter and receiver

Extend out the antennas of transmitter and receiver.

Then, switch on transmitter and receiver.

Be sure to confirm carburetor on neural position

wheel ratate freely, and never adjust the accelero-

grap to the maxim position.

6. Over choked

Engine cylinder is flooded with fuel, plug is wet and recoil

starter is heavy, remove plug/pull recoil starter for 20-30

times to discharge the fuel.

7. Stopping engine
