N o t e 2 : When setting the freewheel, also check both extreme positions of the throttle shaft control.

shaft control must be in position A
– F I G U R E 1 . Step 2: If the throttle trigger is in the other ex-

CARBURETTOR
IF THE CARBURETTOR SETTING IS INTERFERED WITH BY A PERSON WITH-
OUT THE REQUIRED TECHNICAL KNOWLEDGE, IT CAN RESULT IN POOR
ENGINE OPERATION AND ITS DAMAGE.
The carburettor is a vital part of the engine and it requires highly sophisticated adjust-
ments. Most adjustments should be left for the JetSurf™ sales representative who has the
required knowledge and experience.
The carburettor has three basic adjusting
screws:
1 – A screw for adjusting the freewheel revolu-
tions (a freewheel screw)
2 – A screw of the freewheel jet L
3 – A screw of the main jet H
Screw adjustment – p o s i t i o n s 2 a n d 3
are ALWAYS to be left to the seller.
PROCEDURE OF FREEWHEEL SETTING:
Required tools: Allen key 2.5 (spanner No 8 for the back nut)
N o t e 1 : Freewheel screw – p o s i t i o n 1 – it is secured with a back nut from below. If you adjust
the freewheel, FIRST LOOSEN THIS NUT . When the freewheel has been set, retighten it.
The freewheel must be set at the operating speed of the engine (the engine should be running for
some time).
The screw for setting the freewheel revolutions ( p o s i t i o n 1 ) is set by the manufacturer in such
a way that the engine keeps running for a while by itself when started on land (without requiring any
throttle control).
If the engine stops by itself, it is necessary to tighten the freewheel screw
( p o s i t i o n 1 ) to the right
by half a turn. Tightening can be repeated as required.
If the engine revolutions are too high (it does not switch off in the freewheel), the freewheel screw has
to be loosened by turning to the left.
