Carburettor Adjustment - Carson Helldevil Notice D'emploi

1. Initial operation of the engine
Always check if the air filter is mounted correctly and firmly before starting the
engine. The basic adjustment of the engine is set by the factory. The mixture
of petrol an lubricating oil should be 1:25 which means a share of 4% 2-stroke
lubricant (5L petrol / 200 ml lubricant).
Suitable is Super or Superplus petrol.
3. Starting the warm engine
Leave the choke flap open, press the primer pump and activate the rope starter.
To turn the engine off, press the ignition switch until the engine stops.

4. Carburettor adjustment

The adjustment of the carburettor is pre-set by the factory to the local conditions.
Depending on air filter, exhaust silencer and operating conditions a correction
may be necessary.
Drive the car at medium rpm until the motor has reached his operating tempera-
ture. If the engine decelerates a little during acceleration then it runs to lean. In
this case open the anti clockwise. If the engine revs up only slowly stammering
and with clouds of smoke coming out of the exhaust, the engine probably runs
with a too rich mixture. In that case you should close the 1 clockwise.
In order to adjust maximum rpm lift the rear wheels and set the throttle of the
warm engine to the wide open position for a short time.
Now you can turn the full throttle adjusting screw. If the mixture seems too lean
turn to the left, if it seems too rich turn to the right.
ATTENTION!
Don't drive the engine in a no-load condition for a longer time at maximum
speed. In most cases the idling adjustingscrew has to be reset if adjustments at
the No-load adjusting screw 1 or Fullload adjusting screw 2 have been made.

2. Starting the cold engine
Close the carburettor throttle valve or set it to the idling
position. Now shut the choke flap at the carburettor. Press the primer pump at
the carburettor until it is filled with fuel. Slowly pull out the rope starter until you
feel a first resistance, then pull strongly until the engine ignites audible.
Normally the engine will stop again after this first ignition. Now open the choke
flap and pull the rope starter once again until the engine runs.
To turn the engine off, press the ignition switch until the engine stops.

5. Basic adjustment of the carburettor
The specified values serve as reference. In some cases the carburettor has to
be readjusted. If you get the feeling that the No-load adjusting screw 1 or the
Fullload adjusting screw 2 is completely misadjusted then close both screws
1 + 2 carefully. Afterwards open the adjusting screw clockwise corresponding to
the values below.

During the first two tank fillings you should avoid maximum speed under noload
condition as well as longer full speed drives on flat areas.
Before the first start we recommend to check the range of your radio control
system while the engine is running. Never operate the engine in closed rooms
without sufficient ventilation. Further safety instructions are enclosed with the
engine.
