The spacer plates and
'0'
rings used at this joint cct as insulators to absorb vibration
and prevent frothing of fuel i n the float chambers. It i s essential that the carburettor
mountings are not overtightened, as the
' 0 '
rings may be displaced with a resultant
a i r leak.
A
uniform
1
mrn
gap must be maintained between carburettor and spacer plate, and
between spacer plate and manifold as shown.
