Yes but it will be blocked off by a small welsh plug
The manufacturer has the funny idea that mixtures do not need adjusting after installation so they blank off the adjustment to stop DIY from fiddling as you are meant to take it into a dealer and pay for it

SOURCE: carburetor idle mixture adjustment for lean burn chrysler engines

On a carbureted engine(the days of old) I had a method of my own
which always seemed to do really well.
Warm up the engine to operating temperature and make sure there is no
operation of the automatic choke.This should mean that the choke flap in the top of carb is standing vertically offering no resistance to airflow.
Hook up a tachometer if the car has'nt got one.
Note the idle speed in PARK.
Turn the fuel/air adjusting screw underneath carb's right or left sideI(NOT the idle speed set screw) IN and note the rpm as you do.If it raises a little,you are getting close.
Go ahead and turn that screw in all the way and lightly seat it(count the turns in from the highest idle reading),then back it out to the highest reading.NOW turn it in slowly until you see the RPM drop slightly.
Now back it out a little so you are at peak RPM again.
REPEAT this with the other side's fuel/air screw.
After you have gained this higher RPM (maybe), then set the idle speed control screw to desired RPM, and be sure to get in the car and while holding the brake,put the car in DRIVE to make sure the idle doesn't drop too low. don-ohio (:^)

How to adjust a carburetor

this sounds more like you need the carb rebuilt to clean out all the dirt in the small passages and replace the needle and seat as well as the float. the idle air mixture screw are at the front of the carb at the base one for each barrel the carb has. this year should have tamper proof plugs covering the mixture screws which the carb will have to come off to remove them.

1986 dodge ram 225ci slant six and a single barrel holley carb

Start with the idle needle screw first, the idle mixture screw. Seat it all the way in, first-don't overtighten and damage it, just seat it lightly, and back out two full turns. Run the engine and set the adjustment by ear to get your best lean idle: start turning the screw in (clockwise) 1/8 or 1/4 turn at a time till engine stumbles, dies, or runs rough. Keep the engine running, and turn screw out (counterclockwise) a little at a time till you hear the idle dropping. Now between those two settings is your best lean idle. Turn the screw in, a little at a time and wait for engine to respond, tiill you get the highest idle speed. Now set the other idle screw, curb idle, to the idle setting for your truck, probably about 700 rpm. You can move back and forth between the screws to get the best steady idle. Just don't over do it on the idle mixture screw.
Good luck.

Hello:;
This sounds like a fuel problem at the carb. What it's doing is termened hunting a nd can generally be corrected by a simple adjustment of the carb. Engine at idle and neutral set rpms at lowest idle , around 640 rpms. then adjust the a/f ratio screws to balance carb. Screw both screws all the way in, do not force ,or needle and sear damage will occir. Now back each out to 1.5 turns That is your start point Adjust one screw in and out slowly until you you feel its best effact on ide whicjh should slightly increase. repeat with other screw, in and out slowly . listening to the engine idle. if idle has increase due to your adjustmebt, repwat process after lowering the idle speed again with the idle screw. When you get to the point the screws no longer affect the idle the engine show sound and run smoothly at idle, make sure you resert the idle to 650rpms for an automatic trans and 650-750 for manual trans. I hoped this helped- good luck.. If it still does it, the carb may nrrd the float checked and st.

That is the choke adjustment,have you checked your timing on the motor and check and see if the vacum pod on the distributer is working. also check your vacum lines for any tears or cracks in them.
