Idle adjustment screw, where is it?

Nevermind, i found this and got my car idling and running like new, aside from the blue smoke out the back.

I'm curious if i did this correctly, i adjusted the idle to around 750, turned the air/fuel clockwise until it just barely started sputtering (i could've gone more), then back 1/2 turn, this raised the idle to 1,200, i backed the idle back to 750 and kept doing this back and forth.

Is clockwise rich or lean? I'd kind of like it lean it a little more than it should be for fuel economy.

yes it should idle after about 2-3 min at 750, you turn it clock wise to tighten it up(lower rpms) and counter clock wise to up the rpms.


you can turn it kinda a lil bit till it actually shows an increase in rpms. just fiddle with a it a lil bit and keep checking rpms, u should know when its starvin for gas and when ur gettin the right amount at 750
