Choke Unloader
- Hold throttle fully open, and lightly press choke valve toward closed position. Using a specified drill or pin gauge, measure specified choke unloader clearance between lower edge of choke valve and air horn wall.
- To adjust, bend choke unloader tang that contacts fast idle cam. Bend tang toward cam to increase clearance and away from cam to decrease clearance. Do not bend unloader tang downward from a horizontal plane. See Fig 1.

- After correct adjustment is obtained on Jeep models, open throttle until unloader tang is directly under fast idle cam pivot. Make sure there is.070" clearance, between unloader tang and fast idle cam.
- On all models, operate throttle after adjustment. Make sure that tang does not stick or bind against any portion of the linkage or carburetor casting.
