my idle is a bit high and i was wondering which screw is the idle and which is the air/fuel mixture . i dont want to tinker with the air fuel and mess everything up https://www.nopistons.com/forums/pub...IR#>/smile.gif

it is down under where the throttle cable is attached on the right.



The one in the center of the pic is the mixture.

thats an 80 and earlier carb, so theres an idle air, and idle fuel. the big one is air, small one is fuel.



they interact, so it takes a while to get it right.



the car does a lot of its cruising on the idle circuit, so you want the idle as lean as you can get it.
