disassembly.

Keep disassembled parts in order. Apply oil when
necessary. Take special care to keep the fuel system parts
from intrusion of dust and dirt.

be
restored to their respective components from
which they were removed at diSassembly. This means that
all
parts must be
set
aside separately in groups, each marked for
its component, so that the same combination or set can
be
reproduced at assembly.
• Pay attention to marks on assemblies, components and
parts for their positions or directions. Put on marks, if
necessary,

accurately during removal and cleaning.
