On a cold engine, place the throttle midway between the "SLOW" and "FAST"
positions and push choke lever forward into the "ON" position. Turn ignition
switch to the "start" position. Release the switch as soon as the engine starts.
IMPORTANT: DO NOT crank the engine continuously for more then ten (10)
seconds at a time. If the engine does not start, allow a 60 second cool-
down period between starting attempts. Failure to follow these guidelines
can burn out the starter motor.
After starting a cold engine, gradually return choke to the "OFF" position as the
engine warms up.
On a warm engine, place the throttle midway between the "SLOW" and "FAST"
positions and leave the choke in the "OFF" position.
