- ADJUSTMENT NOTE: If preliminary adjustment required to warm-up engine, set each idle mixture screw 1-1 1/2 turns out from a lightly seated position. On air conditioned cars (except Chevelle, Corvette, & Rambler), operate air conditioner for 20 minutes and then set idle speed with air conditioning operating. On cars with Vacuum Parking Brake Release, disconnect vacuum line at vacuum power unit and plug this line (necessary so that idle speed can be set in "D" with brakes set). On cars with Alternator (except Chevelle, Corvette, & Rambler), turn on headlights to place alternator under load. On automatic transmission cars, idle speed should be set with selector lever in "D" (Drive) or "N" (Neutral) as indicated.
