Preparing fuel
The engine is provided with an integrated fuel pump to get fuel to the
carburetor. The carburetor features a manual pump (B) with a transparent
cover to see the fuel flow. Follow the steps below to start the engine.
Be sure you understand all engine instructions before attempting to start the engine. Turn on the transmitter
first, then the receiver before starting the engine.
1. Pump the primer bulb on the carburetor(
B
in
Figure M)
until it is filled.
2. Set the choke lever(
A
in
Figure M
) as shown.
3. Pull the starter cord 3 times
slowly
for the fuel
to get in the cylinder.(Do not pull the cord fast
and more than 50-60cm)
4. Set the choke lever as shown.
5. Pull the starter cord rapidly 5-6 times until the
engine starts.(Do not pull the cord more than 50-60cm)
6. When the engine starts, set the idle if its too high
(vehicle moves at idle) or too low(engine stops running
from the idle screw shown in Figure N .
7. If the engine does not start set the carburetor to
default settings as indicated above.

Figure M
Shutting the engine off
Push engine stop switch E shown in Figure M . (Cut the body from the indicated
area in order to access the switch when the body is mounted. See page 12)
Slight adjustments of the carburetor might be needed depending on the external factors such as mixture,
spark plug, muffler and environmental factors(air pressure, humidity and temperature).
Fine-tuning idle and full throttle settings will only work after the engine is fully broken in. The factory settings
provide a rich mixture that results in a significant blue smoke from the exhaust.
In case the idle-mixture needle L or the main needle H were accidentally altered, turn the setting screws H
and L clockwise as far as they will go. Afterwards, turn the H screw 1hour - 5mins turns counter-clockwise
and the L-screw 1 hour - 5mins counter-clockwise. (As explained in
Figure O
below)
