Motor Settings

The carburettor is perfectly pre-adjusted for the first runs ex works.
A rich carburettor setting is used to sufficiently supply the motor with lubrication during 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 Setting of 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. The adjustment screws explained below are shown in figure 5.
Write down any changes made so that you can easily re-create the initial position if the motor run deteriorates.

b) Setting the Idle Mixture Adjustment Screw (L)

• Put the motor to operating temperature by driving.
• If the motor does not accept throttle well, the idling mixture is too lean. Turn the idle mix adjusting screw anticlockwise
(towards the left) to make the mix richer.
Adjust the setting gradually by about 1/8 turns of the idle mix adjusting screw anti-clockwise.
• If the motor only accepts throttle stuttering and under strong development of smoke, the mixture is too rich. Twisting
clockwise (to the right) makes the mixture leaner (the fuel share is reduced).
Adjust the setting gradually by about 1/8 turns of the idle mix adjusting screw clockwise.

c) Setting the Main Nozzle Needle (H)

• Lift the boat from the water and let the operationally warm motor run at full throttle for a short time.
• The full throttle mixture at the main nozzle needle can now be set in steps of 1/8 turn.
Turn the main nozzle needle clockwise if the mix should be leaner.
Anticlockwise to make the mix richer (to increase the proportion of fuel).
• For a long motor service life, prefer a slightly rich carburettor setting to set the main nozzle needle.
For this, twist the main nozzle needle (H) slowly in small steps so that the engine reaches its maximum speed briefly
after the control signal „full throttle" and runs smoothly without stuttering.
Then turn the main nozzle needle counter-clockwise by about 1/8 turn to increase the fuel share (= rich carburettor
setting).
• After each engine running (tank filling), allow for a sufficient cooling stage (approx. 10 min).
