l) Starting the Engine
General information on Combustion Engines
When putting the new engine into operation, you have to observe a certain run-in time. During the run-in time, engine parts are tuned to one
another, whereby maximal capacity is reached and premature wear is prevented.
Thus, the run-in procedure must be carried out with the highest accuracy!
Preparations
• Oil the air filter slightly in order to filter out dust particles
• Open the tank lid and fill in the fuel.
The wheels must be freely suspended in the air! Place the model e.g. on a suitable car stand.
Starting the cold engine
The carburettor is equipped with a built-in membrane pump, which is
activated as soon as the engine runs.
Thus, the alternating over and under pressure in the housing of the crank
shaft is used in order to convey the fuel in the carburettor. For start up,
the carburettor is equipped with a manual pump with which the fuel is
conveyed into the carburettor. This manual pump consists of a transpa-
rent rubber cap, which also serves as gauge glass for a visual check of
the fuel supply into the carburettor.
• Close the choke valve (lever vertical).
• Actuate the manual pump until the "gauge glass" is completely filled
up with fuel and the latter reaches the carburettor.
• Pull the cable pull starter once until the ignition produces an audible
effect.
• Open the choke flap again (lever horizontally) and pull the rope starter
with vigour until the engine starts. Hold the model firmly with one hand.
Attention!
Never pull out the cable starter all the way but only to a
maximum of 3/4 of its length. Determine the length of the
pull starter by pulling it out slowly without ignition! Never
pull out the cable starter by force!
• In case the engine stalls again immediately after the first start up, close
the choke valve and pull the cable pull starter once more until the engine
starts running again.
• Once the engine starts, let go of the rope starter and set the throttle/brake lever on the remote control transmitter to idle speed.
• Open the choke valve again halfway and let the engine run for approx. 3 to 5 seconds.
• Open the choke valve completely (lever vertically) and let the engine warm up for approx. 2 to 3 minutes.
Attention!
If the choke valve remains shut for too long or if too much fuel was pumped into the combustion chamber and the crank case, the mix becomes too
rich and the engine is flooded. In such a case, you will need to exert more effort to actuate the cable pull starter. Refrain from further starting
attempts and remove the excess fuel in order to prevent damaging the cable pull starter and the engine!
For this purpose, proceed as follows:
• Unscrew the spark plug and let the electrodes dry.
• Open the choke valve completely
• Pull the cable pull starter through a few times
• Insert the spark plug again
• Repeat the start-up process.
