5. Setting up the R 95 engine.
Your new engine does not require a lot of set
-
ting up. It is essentially only the carburettor
that has varying setup alternatives.
1.
Start with a default setting for the carburettor.
Carefully turn both of the adjusting 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 adjust
-
ment screw so that it just misses making con
-
tact 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 continues 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
centrifugal clutch engaging and thus begin
-
ning 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 un
-
til 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 driv
-
ing 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 splutter 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 cyl
-
inder 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 cor
-
rect setup then it may be time to clean the
carburettor. See the section about servicing
the engine.
