Relationship with throttle opening (XE 125 version)
The flow of fuel through the main system of the carburettor
is controlled by the full jet and then further regulated by
the area between the atomizer and the taper pin. In the
relationship between fuel flow and throttle opening, fuel
flow refers to the diameter of the straight portion of the taper
pin around the 1/8 to 1/4 throttle opening, while the 1/4 to
1/1 throttle opening refers to the initial position of the taper
and the position of the clip.
Therefore, the fuel flow is balanced at each stage of the
throttle opening by a combination of the diameter of the
straight portion of the taper pin, the initial position of the
taper and the position of the clip.
