STARTER SYSTEM
Pulling the starter cable G) , fuel is drawn into the starter circuit from the float chamber @ _
Starter jets (@, @) meters this fuel, which then flows into fuel pipe ® and mixes with the air com-
ing from the float chamber. The mixture, rich in fuel content, reaches starter plunger ® and mixes
again with the air coming through a passage extending from behind the diaphragm.
The two successive mixings of fuel with air are such that proper fuel/air mixture for starting is produced
when the mixture is sprayed out through starter outlet port (j) into the main bore.

FLOAT SYSTEM
Floats G) and needle valve 0 are associated with the same
mechanism, so that, as the floats G) move up and down,
the needle valve 0 too moves likewise.
When fuel level is up in float chamber @ , floats G) are up
and needle valve 0 remains pushed up against valve seat.
Under this condition, no fuel enters the float chamber @ .
As the fuel level falls, floats G) go down and needle valve
o unseats itself to admit fuel into the chamber @ .
In this manner, needle valve 0 admits and shuts off fuel
alternately to maintain a practically constant fuel level in-
side the float chamber @ .
