Motor Settings

The carburettor is perfectly pre-adjusted for the first runs ex works. A rich carburettor setting is used to supply the
motor sufficiently with lubrication in the run-in phase. This is shown by strong white smoke development from the
exhaust.
The rich carburettor setting should be maintained for the first 2 - 3 tank fillings. Additionally, do not use any long full-
throttle phases and run in the motor carefully with different speeds.
a) General Information on Setting the Carburettor
Depending on mixture used, spark plug, muffler and ambient conditions like barometric pressure and humidity, small
changes in the carburettor setting may be required. The fine settings of idle and full throttle are only possible with the
engine well run in.

Important!
The carburettor is already in the best basic setting ex works. If the motor cannot be started at initial commis-
sioning, first look for the problem elsewhere before turning the carburettor screws.
Before twisting a setting screw, write down its original position. This way, you can turn it back to the previous
position if there are any problems later.
Make the settings in small steps only. This means that the respective screws must only be turned by 1/8 turn
at most before checking the settings in practice.
Never turn all 3 screws at once. This will make it impossible to successfully start the motor.
