H: 0,75 turn
These are the minimum settings that should
not be lower
5. Setting up the Raket 95
engine.
Your new engine does not require a lot of
setting up. It is essentially only the carbu-
rettor that has varying setup alternatives.
1.
Start with a default setting for the carbu-
rettor. Carefully turn both of the adjust-
ing screws for High Speed (H) and Low
Speed (L) the whole way so that they
are fully closed. After that, open the High
Speed screw (H) 0.75 turns and the Low
Speed screw (L) 2.25 turns.
2.
Next you should screw out the idling
adjustment screw so that it just misses
making contact with the lever on the
throttle shaft. After that, screw in the idling
adjustment screw 1.5 turns. This is now
the default setting for the carburettor that
guarantees that you will be able to start
your engine.
3.
Start the engine. If it stops as soon as you
no longer press the start button, but con-
tinues to run if you carefully give throttle,
then you can try screwing in the idling
adjustment screw by half a turn. Don’t
overdo it however, because the engine
should be able to idle without the centrifu-
gal clutch engaging and thus beginning to
pull the kart along with it.
4.
Now you can drive a lap or two of the
track so that the engine warms up.
5.
Begin the fine tuning with the Low Speed
screw (L). Allow someone to hold the
brake to ensure that the kart cannot begin
to roll, and press quickly on the throttle.
The engine should answer directly and
increase speed until the centrifugal clutch
engages. If the engine hesitates or even
stops then you should test the effect of
slightly increasing the Low Speed screw.
Start with half a turn. When you have
found a setting at which you can apply the
gas and the engine responds immediately
then it is time to move onto the setting of
the High Speed screw (H).
6.
Drive a few laps of the track so that the
engine is really warm. Listen thereafter
to how the engine sounds when you are
driving on the track’s longest straight. The
High Speed screw is correctly adjusted
when the engine begins to splutter at the
very end of the straight. If it starts to splut-
ter any earlier then you should carefully
screw in the High Speed screw one tenth
of a turn. WARNING! Do not overdo it
and screw in the High Speed screw too
much, because then the engine will not
receive enough fuel and as a result not
enough oil, which can lead to piston and
cylinder damage. The High Speed screw
should always remain opened at least a
0,75 turn.
7.
When you have found exactly the right
setting for the High Speed screw you
should check the settings of the Low
Speed screw and the idling adjustment
screw again. You can feel satisfied when:
- the engine idles easily without pulling
the kart, and you hear the occasional
pinging sound from the clutch but not so
often.
- the engine responds directly when
you apply the gas, both when idling and
when you are driving on the track and, for
instance, have taken your foot off the gas
going into a curve and then apply the gas
again.
- the engine winds up properly on the
track’s straight sections, but begins to
splutter at the very end of the longest
straight.
8.
If you find after having driven for a while
that you are no longer able to achieve a
correct setup then it may be time to clean
the carburettor. See the section about ser-
vicing the engine.
