OPERATION
Low Air Temperature 10°C (50°F) or below:
1. Follow steps 1 - 2 under "Normal Air Temperature."
2. When engine rpm begins to pick up, operate the choke lever
to keep fast idle at 2,200- 2,800 rpm.
3. To speed warm up, open and close the throttle, keeping
engine rpm below 2,800.
4. About 5 minutes after the engine starts, push the choke
lever up all the way to Fully Closed (A).
5. Continue warming up the engine by opening and closing the
throttle until it will idle smoothly.
CAUTION:
• Snapping the throttle or fast idling for more than about 5
minutes at normal air temperature may cause exhaust pipe
discoloration.
• Extended use of the choke may impair piston and cylinder
wall lubrication.
Flooded Engine
If the engine fails to start after repeated attempts, it may be
flooded with excess fuel. To clear a flooded engine, turn the
engine stop switch OFF and push the choke lever up to Fully
Closed (A). Open the throttle fully and crank the engine for 5
seconds. Wait 10 seconds, then turn the engine stop switch
ON and follow the "High Air Temperature" Starting Procedure
(page 63).
