Throttle control

First, check whether the throttle control line is deformed,
twisted or damaged.
Then, measure the throttle bar free stroke. Turn the bar to
lean it against one side of the free stroke, and draw a straight line
between the bar and the balance weight with a mark pen, and then
turn the bar to lean it against the other side of the free stroke;
measure the distance the straight line staggers, i.e. the throttle bar
free stroke.
Free stroke 2-6mm.
If the free stroke is insufficient or too big, make adjustment.
Adjusting methods:
Retaining nut B
Retaining nut A
Fine adjustment:
Pull open the rubber lagging, unscrew the retaining nut A, and
turn the adjusting solenoid to adjust to a satisfied free stroke. And
then screw up the retaining nut A and mount the protective rubber
lagging.
Coarse adjustment:
If the fine adjustment is not satisfying, separate the throttle
control line with throttle valve body and unscrew the retaining nut B
to make adjust the free stroke in a larger range. Screw up the
retaining but B after the adjustment.
Check whether the throttle can turn smoothly from full open to
full close at any position. If there is clogging, adjust or replace it.
Warning

dangerous operation, rotating the handle, not full throttle to
the free stroke can make the engine speed increases suddenly.
