WARMING UP ENGINE

1) After the engine starts, return the choke
knob to the half-way position. For
approximately the first 5 minutes after
starting, warm up the engine by operat-
ing at one fifth throttle or less. After the
engine has warmed up, completely push
in the choke knob. (Failure to do so will
shorten engine life.)
NOTE:

approximately 30 seconds after starting.

warming up the engine.
