However, if the engine speeds up momentarily and then cuts outs
abruptly when 100% throttle is applied, the mixture is too lean. In this
case, turn the low-speed needle counter-clockwise in one-hour
increments until the car accelerates quickly and smoothly.
3. The idle adjustment screw should be set so that the engine runs just fast
enough to maintain idle speeds without dying when the throttle is at the
neutral position. Increase idle speeds by turning the idle adjustment
screw clockwise and reduce idle speeds by turning the adjustment screw
counter-clockwise.
When the adjustments are set correctly, light smoke will be visible from the
exhaust and the engine RPM and acceleration will be strong and smooth.
Continually changing atmospheric conditions (temperature, humidity,
barometric pressure) mean that your engine will always require small
adjustments to optimize performance. Changes in altitude will also require
tuning adjustments.
