10.4 Carburettor adjustment
The carburettor has been adjusted optimally at
the factory. Depending on the operational
altitude (mountains or low lying areas) a re-
adjustment of the carburettor may be required.
Mod.: Carburettor with limitercaps
The carburettor has 3 adjustment screws:
• Idling set screw "T" (24)
• Low speed mixture screw "L" (25)
• High speed mixture screw "H" (26)
The regulating screws for idle mixture "L"
(25) and full load mixture "H" (26) must
only be adjusted by qualified mechanics.
Turn the idling set screw "T" (24) to adjust the
idling speed to the data provided in the
technical specifications. An engine speed
counter should be used for this job.
• If the idling speed is too high, turn the idling
set screw "T" anti-clockwise.
• If the idling speed is too low (engine stops)
turn the idling set screw "T" clockwise until
the engine runs smoothly.
If the idling speed cannot be set correctly with
the idling set screw "T", an authorised service
centre should be requested to tune the
carburettor.
The following instructions are for
authorised service shops
Using the D-CUT carburettor:
Key (SOLO part no: 00 80 537) to correct settings
on the idle mixture screw "L" (25) and on the
full load screw "H" (26).
Using the carburettor with limitercaps:
The regulating screws for idle mix and full
charge mix can only be adjusted in a limited
range.
Clean the air filter before adjusting the low
speed adjustment screw!
Let the engine run warm before adjusting the
engine speed.
Medium engine idling speed = 2800 rpm
Max. Admissible engine speed = 6700 rpm
The carburettor is tuned for optimal
engine performance. An engine speed
counter is required to adjust the
carburettor correctly!
Do not adjust the engine to a higher speed.
Excessive engine speed can lead to major engine
damage!
