The negative (—) terminal is grounded at the starting motor. IGNITION.—Breaker contacts separate .020 to .025 inch. When condition of contacts affects the ignition, resurface with a 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.—Breaker contacts begin to separate when the piston entering power stroke is on top dead center, spark control lever and breaker assembly fully retarded.
