SmartCarb™
The channel, marked by arrows, connects the
carburettor's measurement chamber with inlet air
in the inlet elbow. Pressure equalisation between
these allows the carburettor to provide the right
fuel/air mixture regardless of how fouled the filter
may be. This is the operating principle of Smart-
Carb™.
7. Make sure the gasket between the carburettor
and inlet elbow is fitted with the hole facing the
channel side in the inlet elbow.
NOTE! Important! It is essential that the inlet
elbow has a perfect seal to the air filter and
carburettor.
Inlet manifold
The inlet manifold connects the carburettor to the
cylinder. The rubber pipe dampens vibrations and
provides heat insulation for the carburettor. The
inlet manifold consists of two separable base units.
The impulse channel, connects the carburettor
pump diaphragm with the crankcase.
