Standard Jetting

L: 2,25 turn

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.

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.

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.

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.

Now you can drive a lap or two of the

track so that the engine warms up.

Begin the ne 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).

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.

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 satised 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.

If you nd 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.
