5) The Crew Chief operates the throttle control with his
right hand and provides machine stability while holding
the remaining handle with his left hand. The Crew Chief
rotates the throttle control counterclockwise (to open)
half way against its stop. The Crew Member closes the
engine choke by pulling the control lever located above
the carburetor out to its detent position. FIGURE 12.

Do not apply excessive force when pulling or
pushing the choke control lever. Excessive
force can damage the carburetor.
6) The Crew Member pulls the recoil starter handle until
engine compression is felt. Then he gives a fast, short,
steady pull. Allow the starter rope to retract slowly. If
the engine does not start in three pulls, consult the
material supplied by the engine manufacturer for
specific information. As the engine warms up, the Crew
M
ember pushes the choke lever in to its detent
position.
7) Normally, an engine that has not been run for some
time requires three to five pulls before it will fire. On the
other hand, a recently run engine will usually start on
the first or second pull. In cold weather, initial starting
will require additional pulls because an extremely rich
fuel/air mixture is required.
8) Allow the engine to properly "warm up" and operate
without the requirement for engine choke. Check for
proper centrifugal clutch operation, excessive
transmission noise and/or vibration.
9) Stopping the Hole Digger is accomplished by
rotating the twist grip throttle control clockwise to its
maximum, closed position and allowing the throttle arm
to engage the ignition cut-off switch. FIGURE 13.
