4-14 FUEL SYSTEM
STARTER (ENRICHER) SYSTEM
Pulling the starter (enricher) plunger causes fuel to be drawn into the starter circuit from the float chamber
1
.
The starter jet
2
meters this fuel. The fuel then flows into the fuel pipe
3
and mixes with the air coming from
the float chamber
1
. The mixture, rich in fuel, reaches the starter plunger
4
and mixes again with the air
coming through a passage extending from behind the diaphragm.
The two successive mixtures of the fuel with the air provide the proper air/fuel mixture for starting.
This occurs when the mixture is sprayed through the starter outlet port
5
into the main bore.
NOTE:
A starter (enricher) system is operated almost the same way as a choke.
FLOAT SYSTEM
The float
1
and needle valve
2
work in conjunction with one
another. As the float
1
moves up and down, so does the needle
valve
2
.
When there is a high fuel level in the float chamber
3
, the float
1
rises and the needle valve
2
pushes up against the valve
seat. When this occurs, no fuel enters the float chamber
3
.
As the fuel level falls, the float
1
lowers and the needle valve
2
unseats itself; admitting fuel into the float chamber
3
.
In this manner, the needle valve
2
admits and shuts off fuel to
maintain the appropriate fuel level inside the float chamber
3
.
