ADJUSTMENT OF THE CARBURATION
(Pic. 25)
The manufacturer has adjusted the carburettor before delivery.
If you are not totally sure how to control this type of adjustment,
avoid any action since this carburettor is quite stable at any
heights and temperatures.
A rich engine vibrates and consumes too much petrol and a
poor engine is more regular but gets hotter more often; and it
becomes dangerous and can produce own damages. This is
known as “holes” in carburation.

CARBURATION POOR JUST RICH
WALBRO CARBURETTOR
It could be necessary to change carburation according to the season —spring/summer and
autumn/winter—, and to the altitude. We recommend this procedure to be done by an expert.
Low-medium regime carburation can be adjusted using the longest screw 1 (PICTURES 25
and 25B). Turning left (open) the mixture will enrich and turning right (close) will deplete.
Adjustment by default is 1 ½ turns starting from closed position. These adjustments will be
done every five minutes, (scale according to a watch measurement).
If the minimum is very poor, starting up will be difficult and ac-
celerating will fade it away. If minimum is very rich, it will vibrate
and slowly loose RPM when accelerating. Besides, exhausting
fume will be excessive. Screw 2, shorter, adjusts idling regime
opening choker plate at is minimum. Idling regime: Adjust until
it reaches 2100 – 2200 RPM (PICTURE 25C).
NOTE: in order to adjust it, you should test it every one millimetre, since it is very sensitive.
