Im havent the worst time finding this screw on my 89. I know there is a srew on top of the throtle body for air. where is the idle screw or the rich lean screen. I need a pic becuase Ive herd 10 different answers or a acurate description

 

No 1989 model has it.
Only 1986 to 1988 models have it.
That's probably why you can't find it.
