Fast Idle (1973 Models)
Check that mixture control cam lever, on both carburetors (if equipped), returns to its stop. Check that mixture control cables are neither too slack nor too tight. Pull choke control knob out and insert a 5/16" drill or gauge rod between fast idle cam and stop. Adjust fast idle screw until it lightly touches cam. Repeat adjustment on second carburetor (if equipped). Remove gauge, push knob in, then pull out again and check that fast idle speed is to specifications. If necessary, readjust fast idle screws using a suitable air flow meter to maintain carburetor balance on twin carburetor models.
