Carter AVS 4-Barrel: Adjustment: Notes

• AUTOMATIC LEVEL CONTROL EQUIPPED CAR CAUTION:  Idle adjustment must be made exactly as follows to prevent rough idle when compressor operating: Adjust level control reservoir pressure to 70 lbs. (use Schrader valve on compressor), adjust idle mixture with compressor operating, then with compressor off (crimp hose or disconnect hose and block vacuum source), check idle speed and adjust as necessary, finally readjust idle mixture for best compromise between compressor operating and compressor not operating conditions.
