lnspect the
pilot
jet
for
wear or damage
that

have occured
during

Replace all
4
pilot

replacement.
This is
necessary
for
correct
pilot
screw
adjustment
as

other 3
carburetors.
24. Replace
any
O-rings
and
gaskets
that
appear
to
be
damaged
or
deteriorated.
O-ring seals
tend
to
become
hardened
afterprolonged
use and
exposure
to
heat and
therefore
lose their
ability
to seal
'properly.
Replace as
necessary.
