Hi thank you for your question hope this helps.
Adjusting air / fuel mixture
NOTE: A Keihin 2-barrel carburetor is used on these models.
CAUTION Propane is a flammable gas. Observe "no smoking/no open flame'' precautions. Have a Class B-C (dry powder) fire extinguisher within arm's reach at all times.
NOTE: Open the propane control valve slowly; a sudden burst of propane may cause the engine to stall.
NOTE: Some 1984 Accord models may develop a stalling problem at idle. The probable cause of this stalling is a sticking slow mixture cut-off solenoid. If this is the case, the solenoid should be removed and replaced with the updated type of solenoid. Additionally, various cold starting and driveability problems on these cars were cured through the addition of assorted "cold-start'' kits from Honda. Consult your dealer's service department for details.

With the air conditioning operating, adjust the idle at screw B
idle speed adjusting
On carbureted engines, the idle should be checked with the engine at normal operating temperature and the fast idle system fully disengaged. Connect a tachometer to the vehicle following the manufacturers instructions.
Adjustments are made at the throttle stop screw on the carburetor. This is a mechanical adjustment which simply opens or closes the throttle plate a small amount, thus altering the idle speed. On Accords, the throttle stop has a knurled plastic knob to make adjustment easier. The knob, however, is located on the firewall side of the carburetor and may be difficult to reach. The spring on the adjuster also makes the knob a bit stiff to turn.
Accord throttle adjusting screw
NOTE: on Accords, be very certain that you have found the proper screw before making adjustments. Any linkage screw sealed with a dot of paint (usually yellow) is NOT to be altered. These are factory set and, in some cases, are not resettable in the field.
I would also check for vacuum leaks, Also dirty carburetor jets
Let me know Hope this helpsGood luck
David, Thank you. You have been very spacific with your instructions. Can you tell me what you think the reason might be for that car to be stalling when it idlles.
There was water in the fuel filter, and water to the gas tank.
Would it help if I took the plug out of the carborator and shot some gum out of that hole. (rinsed it out)?
