Fuel system
Setting engine speed (RPM )
2.
Warm up the engine and check the idling speed
using a workshop tachometer (see Technical Data
for correct idling speed).
Check that the throttle mechanism functions normally.
Check that the throttle arm (1) (Fig. moves towards low
idle (2) when the throttle mechanism is in idling position
and moves towards the stop screw at wide open throttle
(WOT) (3) when the throttle mechanism is at wide open
throttle (WOT). Adjust the throttle mechanism if neces-
sary. Also check that the air filter and air intake are not
blocked.

4.
If necessary, adjust to the correct idling speed
using the adjustment screw (2).
Check gap (3) again according to point 1.
IMPORTANT! The engine speed (RPM) and
fuel quantity are factory set to give maximum
output and minimum environmental impact. The-
se settings must not be changed
Engine racing (high idling speed)
Warm up the engine and check the engine racing speed
using a workshop tachometer when the engine has no
load at wide open throttle (WOT) (see Technical Data
for correct engine racing speed).
Seals on the fuel injection pump may only be
broken by authorised personnel. Broken seals
must always be resealed
Adjust if necessary as follows:
1.
Slacken off the stop screw (3) so that it does not li-
mit the movement of the throttle arm (1).
2.
Run the engine with no load at wide open throttle
(WOT) and adjust to the correct rev speed using
the adjustment screw (4) (remember to reseal the
screw).
3.
Adjust the stop screw (3) so that there is a clearan-
ce of 0.1 mm between the stop screw (3) and the
throttle arm (1) when the throttle mechanism is at
wide open throttle (WOT).

when the throttle mechanism is in the idling posi-
tion. If necessary: Slacken off the locknut (7) and
adjust until the correct gap is obtained with the
screw (8).
