HOW TO DRIVE.
Before starting an engine the driver should see that the gear shift lever is in neutral position and that the emergency brakes are set. The spark lever should be set at the proper position. If battery ignition is used it is best to have the lever in full retard position, as the spark will occur no matter how slow the engine is cranked. If magneto ignition is used the lever should be advanced slightly as a hotter spark is obtained in the advanced position than in the retarded. There is less probability of a kick back when starting on magneto since it is necessary to turn the engine at a fairly high rate of speed, approximately 100 R. P. M. to generate sufficient current to produce a spark.
The position of the throttle hand control should be set so that the throttle will be slightly open. In case the carburetor is equipped with an air-choking device this should be closed to cause a rich mixture for starting.
The ignition switch should be turned on and the engine cranked by pulling up quickly on the crank handle a quarter turn at a time. If an electric cranking motor is provided depress the starting button and advance the spark. If magneto ignition is used it is best to spin the engine. Crank the engine with the left hand if possible and stand in such a position that if the engine should kick back the crank will not cause injury.
After the engine has started release the choke on the carburetor advance the spark and close the throttle to a position which will prevent racing. If a special dash adjustment is provided for regulating the mixture allow this to remain in a position to cause a rich mixture until the engine warms up.
