NOTE:
Some 1977 V6 engine, automatic transmission equipped models may exhibit stalling and/or stumbling after start up. To correct these conditions on pre-November 1976 produced models, automatic choke may be indexed 2 notches richer than production setting (3 notches rich total). After November 1976, a new choke thermostat will be phased into production with part No. (10756150) stamped on choke cover. Set new chokes to 1 notch rich as these units are calibrated to compensate for richer setting required.
