Remove the air cleaner to access the carburetor.
Note the right side of the carburetor where the accelerator cable is connected.
The cable is connected to the accelerator cam which is stopped by the idle set screw.
The Idle adjustment screw head is pushing down on a spring, which should help Identify the correct adjustment screw.
Be careful not to adjust the smaller mixture screws, unless you have a vacuum gage.
If your Idle is too high you may get after run or knocking. I would set the timing then adjust the idle afterwards.
I hope this helps out since I do not know if the carburetor is stock or not.

My 1987 El Camino stalls when stopping at a stop light (below 5 miles per hour) after it has been driven 20 or more miles. It is equiped with a carberated 305 V8 with automatic transmission.. Starts up...


Does it feel like the engine is stalling or the transmission is not disengaging? You may have a transmission or toque converter problem. If it is your engine you may have an EGR valve issue or an Idle air control issue.

I just rebuilt my F-150 1 barrel Carter carb (1985)once started runs great under all power ranges.Problem? Hard to start.


should adjust the butterfly to about 3/8" opening at 50 degrees farenheit when engine is cold. Usually about 1 mark to the lean side on the choke spring housing. If unsure set the choke to the center mark than richen up one mark at a time until the engine starts and idles up when cold after properly setting choke by fully depressing and releasing the accelerator before cranking. If it doesn't idle up enough turn up the fast idle screw 1/2 turn at a time. Another common problem with the YFA is the choke heat riser tube rusting off at the manifold and the choke not unloading when the engine warms. Install a new riser tube after using a drill bit the same diameter as the tube to drill out the remainder of the old tube in manifold before inserting the new tube and attaching to choke housing.

My 1981 chevy El Camino V6 3.8L 229 idle gets high when engine is hot and when engine gets cold idle drops not sure why can i have any suggestions


Sounds like a problem with your choke. It may just need to be cleaned (linkages and all). If the choke doesn't close after reaching operating temperature, the engine will rev high. This indicates a choke stuck in the open position. Also, you may need to look for a vacuum leak if cleaning it doesn't fix it. On a 1981 GM product, I'd expect the vacuum hoses to be stiff and cracking.
