i) 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 this 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
• The carburettor is already roughly pre-adjusted.
• Before running the engine, blow compressed air into it.
This way you make sure that the combustion chamber is free of dirt which may have gotten into the engine through the spark plug seat.
• Insert a glow plug with the thermal value medium to extra cold (depending on the fuel).
• Oil the air filter slightly in order to filter out dust particles
Never drive without an air filter!
• Open the tank lid and fill in the fuel.
Starting the motor
The wheels must be freely suspended in the air! Place the model e.g. on a suitable car stand.
• Pull the cable starter several times (slowly!) to suck fuel into the carburettor.
• Do this until there are no more visible air bubbles in the fuel hose and the fuel just about reaches the carburettor.
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!
• Place the plug starter on the glow plug with the battery fully charged. Ensure a tight fit!
• Now pull the cable pull starter through until the motor starts up. Hold the model firmly with one hand.
However, never reach into the drive because this could engage the sliding clutch. Risk of injury!
• Once the motor is running, let go of the cable starter and remove the glow plug starter.
Only leave the glow plug starter connected to the engine briefly. Otherwise, the glow plug may burn out prematurely.
• If the pull starter can only be actuated with a lot of force after several unsuccessful start attempts, too much fuel got into the combustion chamber and the
crankcase. The engine was flooded.
Refrain from further start trials and remove the excess fuel in order to prevent damaging the cable pull starter and the engine!
For this purpose, proceed as follows:
• Carefully turn in the main nozzle needle clockwise as far as it will go.
• Unscrew the glow plug and check its glow function
• Place a piece of cloth on the engine and pull the cable pull starter 5-6 times (3/4 of the length!): Fuel is pumped out and evaporates.
• Re-insert the glow plug.
• Unscrew the main nozzle needle with 3 rotations anticlockwise.
• Repeat the start-up process.
If the engine does not start after 10 attempts at the most, proceed as described above or try to locate the error in the troubleshooting table!
