Fist starting of the day
Make sure the ignition switch is off.
Close the choke valve fully.
Set the throttle stick at bottom or 1/8 (2~3 clicks) advanced
from the bottom.
Flip the propeller until the fuel runs out of the carburetor,
then flip 3~4 times more (6~7 times in winter).
(In case of upright and side installation, flip 7~8 more time
after the fuel reached the carburetor.)
Open the choke valve fully.
Turn on the ignition switch.
Tell the helper and onlookers that you will start the engine

Flip the propeller with a Chicken stick or gloved hand to
start the engine. Usually the engine will start with 5~6 flips.
If you have only short runs or the engine does not start
with more than 15 flips, most probably the priming is not
sufficient. Repeat the procedure again.
Note
If the engine does not start after more than 5 times repeat
the procedure, over-priming is suspected.
Check whether the plug is wet or not. If the plug is wet,
replace it or wait until it is dried.
Then, flip the propeller swiftly (15~20 times) with the plug
removed to eject the fuel in the cylinder.
Then, install the plug and repeat the starting procedure.
