1. Fuel flow chart:
A guide to the fuel flow rate according to the
throttle opening.
CAUTION:
If the air intake silencer and air chamber are
removed from the carburetors, the change
in pressure in the intake will create a lean
mixture that could result in severe engine
damage.
Removal of the air intake silencer and the air
chamber do not improve performance char-
acteristics. They must be secured to the car-
buretor during tuning and adjustment, and
must always be in place when the engine is
operated. Examine the intake silencer and
air chamber regularly for cleanliness and
freedom from obstruction.
