shift lever is in Neutral.
3.
Pull choke lever out to ON position when starting
a cold engine and throttle lever to Mid position.
4.
Insert key into ignition switch and rotate it
clockwise to start the engine. Release key when
engine starts. Gradually return the choke lever to the
OFF position (lever all the way in) after the engine starts
and warms up.

Make sure coring head is in the raised position.
Note:
