Description
The drawings accompanying this description do not
correspond with the carburettor on the chainsaw.
They only show the principle for the design and
function.
Design
The carburettor is based on three sub-systems:
The metering unit, A.
The mixing venturi, B.
The pump unit, C.
Fig  22
The jets and the fuel’s control functions are located
in the metering unit (A). Here the correct quantity
of fuel is adjusted for the actual speed and power
output (see figure 22).
The mixing venturi (B) houses the choke, throttle
valve and diffuser jets. Here air is mixed with the
fuel to give a fuel/air mixture that can be ignited by
the ignition spark (see figure 23).
Fig  23
In the pump unit (C), fuel is pumped from the fuel
tank to the metering unit. One side of the pump di-
aphragm is connected to the crankcase and pulses
in time with the pressure changes in the crankcase.
The other side of the diaphragm pumps the fuel
(see figure 24).
