CHANGES, CAUTIONS, CORRECTIONS

"CAP" CARBURETOR NOTE: These "CAP" carburetors are special units used on cars with "Cleaner Air Package" and require special adjustment procedures for Idle Speed & Mixture adjustment and Fast Idle Speed adjustment.
HARD COLD STARTING CORRECTION (All cars with Choke Vacuum Piston in Air Horn): Condition may be caused by choke piston sticking due to gum formation. To correct, remove air horn, squirt carburetor cleaner, lacquer thinner, or alcohol through piston link opening in air horn while operating choke by hand to clean out gum formation and free piston.
1959 CHRYSLER HESITATION OR STUMBLE ON ACCELERATION (Warm Engine): If not corrected by complete engine tune-up and carburetor adjustment install pump connector rod in outer hole of throttle lever. If condition persists, install new Step-up Rods, Carter No. 75-997 or 75-999.
1959 DESOTO FLAT SPOT OR SURGE AT LOW SPEED OR ON ACCELERATION (Firedome Engine with 2871S Carb.): If not corrected by engine tune-up and carburetor adjustment, install new Step-up Rods, Carter No. 75-999. Remove venturi cluster and enlarge inner diameter of two cluster screws to.054" (use No. 54 drill in a pin vise do not use power drill).
1962 DODGE & PLYMOUTH CONSTANT SPEED SURGE CORRECTION (318" Engine with 3241S Carb.): Correct by installing richer Step-Up Rod, Carter No. 75-1600 (to replace standard 75-1605). Make certain float setting is 1/4".
1963 CHRYSLER, DODGE, PLYMOUTH ENGINE RICHNESS DURING WARM-UP (With 383" Engine): If this condition occurs on cars driven at continuous high speeds in warm climates, it may be caused by choke thermostatic coil distortion. Install new coil assembly. Chrysler Part No. 2463159.
1964 367" & 383" ENGINE WITH CARTER 3684S & 3685S CARBURETORS LEAN ENGINE SURGE AT 50-55 MPH CORRECTION: Replace cluster screws, Part No. 101-454 with cluster screws Part No. 101-450.
NOTE: If the above screws ore not available, drill out the lengthwise hole in Part No. 101-454 using a No. 54 drill.

If additional correction is required, drill out idle orifice tubes with a No. 68 drill. In the event that neither of the above corrections eliminate the trouble, replace main jets with new ones. Use the same Carter Part No. I20-284S.
1964 273" ENGINE STUMBLE & SURGE (AT LOW TEMPERATURE) CORRECTION: On early cars, equipped with 3767S & 3768S carburetors, the above condition can be corrected by replacing the Carter No. 120-21 OS main jets with Part No. 120-21 IS. Also install new step-up wires, Carter No. 75-1631 (3767S); No. 75-1616 (3768S), with the new main jets.
NOTE: When making this change, stamp an "A" on carburetor identification tag.
1964 EARLY PRODUCTION 273" ENGINE EXCESSIVE CHOKE ACTION, RICHNESS OR LOADING CORRECTION: This condition may be caused by an incorrect choke assembly. The correct choke will have "AV-816" stamped on the circular cover that travels with the choke rod. The incorrect choke will have "AX-801" stamped on circular cover. If necessary, an incorrect choke may be used temporarily by readjusting it to one notch lean.
1965 CHRYSLER, DODGE, PLYMOUTH FUEL ECONOMY IMPROVEMENT (Auto. Trans. Cars with 361" or 383" Engine & Carter 3850S Carb.): For short trip driving. Choke Vacuum Kick adjustment is critical and correct setting is important for correct performance and warm-up fuel economy. See VACUUM KICK ADJUSTMENT . If carburetor fuel mixture is on the rich side, a one size leaner main metering jet, Carter No. 120-296S may be installed (performance will not be acceptable with this jet if mixture is on the lean side). Also check Ignition Timing and Distributor Advance (mechanical 8: vacuum) performance.
