Fast Idle Setting: Notes

NOTE: Chevrolet and some Pontiac fast idle settings will be correct when "slow idle" speed and choke rod adjustments have been made. On other models, the "On Engine" fast idle adjustment must be made with carburetor installed to insure proper warm-up performance. On some models, an "Off Engine" setting is specified as a preliminary adjustment.
