Rotating the black pod cover controls the choke timing. To rotate the cover, loosen the three Allen
screws that secure the cover to the pod. Rotating the cover clockwise will decrease the amount of
time it takes the choke to pull off, while counterclockwise will increase the time it takes. This
adjustment will depend on your climate and the vehicle it is installed on.
One final note, dependent on which air cleaner air cleaner gasket is used, it may be necessary to put
a slight dimple into the air cleaner to allow the full range of motion of the choke shaft and butterfly.
Failure to do so could result in an engine that is stuck with a high idle, which could make the vehicle
hard to control and stop.
CAUTION: Due to the choke horn's increased airflow design, and dependent on
what air cleaner/air cleaner gasket combination is used, a slight dimple may be
necessary to allow for the butterfly to have a complete range of motion. Failure
to do so could result in a vehicle with an increased idle that could make the
vehicle hard to stop or control.
CAUTION: As with any modification, inspection of the part after completion is a must. Before use,
check the linkage for freeness of operation. Your safety depends on it.
