If the engine is cold or the ambient temperature is low,
close the choke lever fully.
If the engine is warm or the ambient temperature is high,
open the choke lever half-way, or keep it fully open.
(4) Pull the starter handle slowly until resistance is felt. This
is the “compression” point. Return the handle to its
original position and pull swiftly. Do not pull out the rope
all the way. After starting the engine, allow the starter
handle to return to its original position while still holding
the handle. (See Fig.3

wise to the position “ ” (OFF). (See Fig.4
q)
(3) Close the fuel cock.
(4) Pull the starter handle slowly and return the handle to its
original position when resistance is felt. This operation
is necessary to prevent outside moist air from intruding
into the combustion chamber. (See Fig.4
w)
(5) After starting the engine, gradually open choke by turning
the choke lever and finally keep it fully opened. Do not
fully open the choke lever immediately when the engine
is cold or the ambient temperature is low, because the
engine may stop. (See Fig.3

(ON) position and wait for about 10 secounds before
retrying.
Never turn the key switch to the START position while
engine is running.
