Starter System; Float System - Suzuki Katana 1100 Service Manual

4-7 FUEL AND LUBRICATION SYSTEM
STARTER SYSTEM
Turning the choke (or starter) lever allows starting
plunger to draw fuel into the starter circuit from
the float chamber.
Starter jet meters this fuel, which then flows into
starter pipe and mixes with the air coming from the
float chamber. The mixture, rich in fuel content,
reaches starting 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 into the main bore.
FLOAT SYSTEM
Floats and needle valve are associated with the
same mechanism, so that. as the floats move up
and down, the needle valve too moves likewise.
When fuel level is up in float chamber, floats are
up and needle valve remains pushed up against
valve seat. Under this condition, no fuel enters the
float chamber.
As the fuel level falls, floats go down and needle
valve unseats itself to admit fuel into the chamber.
In this manner, needle valve admits and shuts off
fuel alternately to maintain a practically constant
fuel level inside the float chamber.
