Carburettor Adjustment - Carson CRT Betriebsanleitung

1. Initial operation of the engine
GB
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 temperature. 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.

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.
Operating the rope starter
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.
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.
1 No-load mixture adjusting screw
2 Full-load mixture adjusting screw
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.
