resistance is felt, then use steady and rapid motions until the

temperature is very low, it may be necessary to pull the starter
lever several times - this is normal.
e) [Only when the engine is cold] After starting the engine, let it run
for approx. 10 minutes to gain operating temperature - set the
choke lever to the off (down) position.
