FUEL SYSTEM 4-13
MAIN SYSTEM
As the throttle valve
1
is opened, engine speed rises and negative pressure in the venturi
A
increases.
This causes the piston valve
2
to move upward.
The fuel in the float chamber
3
is metered by the main jet
4
. The metered fuel enters the needle jet
5
,
mixes with the air admitted through the main air jet
6
and forms an emulsion.
The emulsified fuel then passes through the clearance between the needle jet
5
and jet needle
7
and is
discharged into the venturi
A
, where it meets the main air stream being drawn by the engine.
Mixture proportioning is accomplished in the needle jet
5
. The clearance through which the emulsified fuel
must flow ultimately depends on throttle position.
