12-6. Choke Unloader (Wide Open Kick).
The choke unloader is a mechanical device that partially
opens the choke valve at wide open throttle. It is used to
eliminate choke enrichment when cranking the engine.
Engines which have been flooded or stalled are cleared by
using the unloader. Adjust it as follows:
a. Hold the throttle in the wide open position. Insert
a 0.310 inch feeler gage between the upper edge of the
choke valve and the inner wall of the air horn.
b. Press a finger lightly against the choke lever. You
should feel a slight drag as the gage is withdrawn. If an
adjustment is necessary, bend the unloaded tang on the
throttle lever to the correct opening.
