6.3 INTAKE SYSTEM
GENERAL INFORMATION
The intake system uses an air filter which is directly
connected to the carburettor and a manifold which
conveys the air/petrol mixture towards the induction
valve.
The intake system can malfunction in the following
ways:
• no or difficult starting or insufficient power (if not
due to other causes):
= Air filter clogged
[ 6.3.A] ;
The air filter is found on the right hand side of the
engine and can be inspected without having to
remove other parts.
The entire body of the filter only needs to be
removed in case of access to the carburettor.
SERVICING PROCEDURES
A) Maintenance of filtering element
1 Clean the area around the filter cover (1).
2 Remove the cover (1) by releasing the rear flap
(2) and remove the sponge filtering element (3).
IMPORTANT! The filtering element must be
kept clean and soaked in oil. Replace it if bro-
ken, cracked or fragmented. Do not use com-
pressed air for cleaning the filtering element.
3 Wash the sponge filtering element in water and
detergent and dry it with a clean cloth.
4 Soak the filtering element with 2 spoonfuls of
clean engine oil and squeeze it several times to
spread the oil evenly (4).
5 Remove any excess oil with a clean cloth.
6 With a jet of compressed air, clean inside the
body (5) of the filter by removing dust and
remains of grass, making sure that the intake
pipe hole (6) is closed so that nothing gets
inside the pipe.
7 Install the filtering element (3) in place and close
the cover (1).
