MAINTENANCE
CARBURETTOR
Idling
For the maintenance intervals, see (PERIODIC MAINTENANCE
CHARTS), under:
– Idling.
To check the idling speed the vehicle engine must be
at normal running temperature. If the check is made
with a cool engine the calibration will be out of tune.
Check
– Run a few kilometres until normal operating temperature
is reached, then stop the vehicle.
– Place it on the stand.
Take care not to touch the hot engine parts with bare
skin, as there is the risk of burns.
– Work from the left side of the vehicle.
– The engine idling speed must be approx.: 2000 ± 200 rpm.
If the engine tends to cut out, without using the throttle control, this means that the idling speed must be adjusted using
the screw located on the carburettor.
Adjustment
– Adjust the screw (1) located on the carburettor (left side).
– TIGHTENING (clockwise), the revs increase.
– LOOSENING (counter-clockwise), the revs decrease.
To check correct operation and if the idling speed remains stable, twist the accelerator handle to accelerate and throttle
down a few times.
Do not adjust the air adjusting screw to avoid altering the mixture settings.
If necessary, consult a Dealer.
