We deliver most of our models with a standard air filter includ­ing foam inlet. This filter is sufficient for driving on grounds
with little formation of dust. As a precaution we recommend
to change or clean the foam inlets more oftenly. Spray foam
inlets with filter oil before use. Please use our K + N filter ad­ditionally if you are frequently driving on Off-Road ground
with high formation of dust (filter and accessories see
FG catalog 2, page 112-114).

1. Initial operation of the engine

Always check if the air filter and also the air filter adapter are seat­ed correct and firm before starting the engine. The basic adjust­ment of the engine is preset by the factory. At high formation of
dust we recommend to seal the connection between carburetor,
air filter adapter and air filter additionally with FG Silicone 6503.
The petroil lubrication should be 1:25 which means a share of 4 %
oil. Suitable is Super or Superplus petrol. We recommend our
FG High Performance Oil for an optimal lubrication (FG catalog
page 109).

2. Starting the cold engine

Close the carburetor throttle valve or rather bring it into neutral
gear. Now shut the choke flap at the carburetor (Solo engine and
Zenoah G230) or at the air filter (Zenoah engine). Press the primer
pump at the carburetor until the pump is full with fuel. Slowly pull
the rope starter until you feel the first resistance, then pull strongly
until the engine ignites audible. Normally the engine will stop again
after the first ignition. Now open the choke flap and pull the rope
starter once again until the engine runs.

3. Starting the warm engine

Leave the choke clap open, press the primer pump and actuate
the rope starter. To turn the engine off, press the ignition switch
until the engine stops.

During the first two tank fillings you should avoid maximum speed
ranges in no-load condition as well as longer full-speed drives on
parking places. The first thing we recommend to check is the ef­fective radius of your radio control system with running engine.
A disturbance on the basis of the ignition system is possible.
To suppress the interference we recommend our metal plug caps
on page 107, FG catalog 2.

Never operate the engine in closed-up rooms without sufficient
ventilation. Further safety instructions are enclosed with the en­gines.

4. Carburetor adjustment

The adjustment of the carburetor is preset by the factory adequate
to the local conditions. Depending on air filter, exhaust silencer and
operating conditions a correction may be necessary.
Drive the engine until it has reached its working temperature. If the
engine decelerates a little during the acceleration, then it runs too
lean. In this case open the No-load adjusting screw L anticlockwise.
If the engine revs up only slowly stammering and under clouds of
smoke, then the engine probably runs with an overrich mixture. In
that case you should turn the No-load adjusting screw L clockwise.
In order to adjust the maximum range of speed, lift the rear wheels
and drive the warm engine shortly at full speed. Now you can turn
the Full-load adjusting screw H to the left (lean mixture) or to the
right (overrich mixture).
ATTENTION! Don’t drive the engine in a no-load condition too long
at the maximum speed range. Mostly the neutral gear adjusting
screw has to be regulated once again if it was necessary to adjust
the engine at the No-load adjusting screw L or Full-load adjusting
screw H.

5. Basic adjustment of the carburetor

The declared values are reference values. Mostly the carburetor has
to be readjusted. If you have the feeling that the No-load adjusting
screw L or the Full-load adjusting screw H is completely misadjust­ed, then close both adjusting screws L + H carefully. Afterwards
open the adjusting screws anticlockwise corresponding to the fol­lowing table.
