How do I set the adjustments for idle higher and gas mixture lower on my 1986 5000cdturbo 5 speed to . I am presently burning to high hydrocarbons for the emissions test (6 where 1.5 is the max co) and haved replaced the o2 sensor.
There is a screw in the throttle body for setting idle mixture.Sometime its hidden by a plug.There is also an adjustment on the top of the K-Jet Injection distributor head.Needs a hex key to adjust.
