Motor will start but it is hard to keep it at idle and the motor revs up and down cant seem to adjust it with the choke any help with this would greatly be appreciated

Replace or clean the idle air control motor. Just a note. It is 32 years old, could be wiring to the IAC motor.

check the cam action on the linkage from the auto choke to the throttle screw.

REPLACE COOLANT TEMP SENSOR..

Sounds like a transmission problem. Change the transmission filter and fluid and make sure it is topped off to the proper level. Have the transmission checked out to ensure there isn't a problem in the torque converter.

The float in the carb is sticking..Buy a can of carb clean and spray it down as good as you can..In every hole and what you can get to...Alot of times this will work without having to take it off and clean it..After you spray it down really good let it sit for about 20 min.That will give it enough time to break down theat old gummy gas build up..After letting it sit Start it up..You may have to hold the gas pedal to the floor in order to start it because of the over satutration of the cleaner..After letting it run for awhile let it idle and go under the hood with it still idling and rev the motor up and closing the choke at the same time..You may have to rev it up a little high..When you rev it up and the motor is racing quick close the choke and the motor will start to die down and rev it a little with the choke on..What this does is by closing the choke when its reving up is it sucks all that crud build up out .You may have to do that a few times but it works great..Good Luck and Have a great day

Even with a rebuilt carb you have to make the adjustments. Check the choke adjustment and set the fast idle. If choke is to tight it will be hard to start and take a long time to idle down. The fast idle sounds like it is high also.

If it's carburetor & has automatic choke, then there is probably a screw at side of carb, by step cam that moves with choke . Back it of a little at a time until you get desired cold idle speed. Make sure you turn step cam to setting it would normally be when cold, and choke on, then turn screw out to lower rpm's. Look for a little rod from choke shaft, down to base or side of carb area, to step cam.

Intake manifold gasket is the most common cause of un-even idle.

IAC (Idle air control) motor is a small motor that adjust the idle.
In a cold AM,start up the car and turn on headlght,high beam,ac and radio.

Look for the IAC to see does it back down the idle as you shut off one item as a time.

IAC can be lube and save.

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.

if the idle goes up and down constantly it will be the iac motor which is common on hondas
