Hi,
Tuning up daughters honda...not sure who was in there prior to purchase, but it idles about 2k+. I've seen the article on throttle cable adjustment, but looking for location and specs for the idle screw and thinking there should also be an air/fuel adjustment screw. Anyone have pics (I'm a visual person) and input, that would be greatly appreciated

 

there is an air/fuel adjustment screw but it is sealed up by a cap and requires drilling the carb body to get to it.
Throttle cable should have a slight amount of slack.
Have you checked the A/C idle boost lever on the drivers side?
Also check the 'letdown' lever on the passengerside.
You'll need a long skinny phillps screwdriver to adjust them.
Another thing that happens in older cars is that the throttle plate [bottom of carb] just wears out it's bushings in the carb body, and causes the throttle plate to hang up, opened slightly.
Vacuum leaks can also cause high idle, choke pull off diaphram, or just the basic idle adjust screw.
