SYMPTOM
The engine may not restart after being shut off
before the engine has been properly warmed up.
The engine may sputter at low RPM for a few
seconds and stall, and cannot be restarted until it
has rested for a few minutes.
The symptom is most likely to occur if the engine is
started and only allowed to run for a brief time
(usually less than one minute) before being shut
off. However, this also can occur after the engine
partially cools from normal operating temperatures.
The symptom can occur when the engine is slightly
warm, but the choke plate is still in the fully closed
position because the auto-choke thermo-wax motor
senses the engine is still cold.
AFFECTED UNITS

GCV160LA0S3TE
CORRECTIVE ACTION
There are a variety of factors that may result in an
improper heat transfer to the Auto Choke System™
thermo-wax which may reduce choke system
performance. In some cases, a sticking auto-choke
control may also contribute to the symptom.
