CHEVROLET MODEL F. B. (1920-21-22) AUTO-LITE GENERATING, STARTING AND LIGHTING SYSTEM REMY IGNITION BATTERY.—Willard, Type SJR-4, 6 volt, 115 ampere-hours. The negative (—) terminal is grounded. IGNITION :—Breaker contacts separate .020 to .025 inch. When condition of con- tacts affects the ignition, resurface with a very fine, flat jeweler’s file or worn No. 00. sandpaper. Oiling:—Refill the cup under the distributor head with soft cup grease and turn down two turns every two weeks. Put a small amount of vaseline on the fiber bumper of the contact arm, using a toothpick. If the car is driven more than 500 miles in two weeks, these attentions must be given every 500 miles. Timing:—Contacts should begin to separate when the pace entering power stroke is on top dead center, spark control lever and breaker assembly in the fully re- tarded position. Firing Order:—The firing order is 1-2-4-3, F Spark Plug Gaps:—Spark plug gaps are .025 to .030 inch. STARTER:—Model ME. Starter is connected to engine through a Bendix drive.
