General information
The carburettor has a float with a fixed jet and a “AUTO-CHOKE” control.
for advice on resolving problems due to carburation.
The carburettor is located on the left-hand side of the engine. For maintenance operations it is necessary
to dismantle the air intake filter in the sequence shown below.
Some of the following operations can be facilitated by removing the engine from the machine.
NOTE: For engine removal operations you should consult the manual specific to the machine on which
the engine itself is mounted.

naked flames or unprotected sources of heat;
- collect petrol in a suitable container with a cap
using a funnel and avoid spilling it on the work
bench;
- remove all traces of spilt petrol immediately;
- check you have connected the pipes before
pouring petrol back into the tank.
