TO START ENGINE.
    See that any dirt which has accumulated on engine while in transit or being installed is removed and the engine properly cleaned up. Fill tank with a good grade gasoline and see that it flows steadily to carburetor. Fill oil and grease cups and follow lubrication instructions as given in later paragraph.
    Put about two priming cupful of cylinder oil in each cylinder. Turn the engine over several times by had to work the oil on the cylinder walls and see that the engine does not bind but turns freely.
    If engine is cold prime each cylinder with gasoline, using about one bowlful of the priming cup. In cold weather starting may be facilitated by priming with about one tablespoonful of high test gasoline or ether. If it is necessary to prime more than two or three times before engine is started, one is liable to wash the lubrication oil from cylinder walls and cause damage to cylinder, piston, and rings.
    To overcome same use a full tablespoon of cylinder oil in each priming cup, turning the engine over by hand before again trying to start the engine.
    Be sure the spark lever is retarded. Throw in the switch; turn on the gasoline; open pet cock in side of engine and start engine by turning balance wheel until gas explodes sharply through pet cock.
    If engine does not start at once and is fitted for make and break ignition, test spark and see it is full and at least 1/4" long. Test contact to see it is correct and that the firing pin is properly insulated. A few drops on kerosene on firing shaft before starting will keep the shaft from gumming up. If engine is fitted for jump spark ignition, the balance wheel handle on one-cylinder and small two-cylinder engines or the Mark No. 1 on balance wheel when placed at top center corresponds with the front piston, being on top center so you can easily tell which is the retard position of the timer handle by seeing the position of handle or No. 1 Mark on the balance wheel when the buzzing of the coil starts.

RUNNING ENGINE.
    As soon as the engine is started, immediately close the priming cup or pet cock. If the priming cups are not closed immediately the hot gases will burn them and render them useless. Advance the spark until the engine speeds up, but not so far advanced as to cause the engine to pound. Adjust the throttle on the carburetor to give the desired speed of engine.
    Positively do not allow the engine to race under any conditions. If the engine is installed where carburetor throttle cannot be reached when releasing reverse gear, have the throttle control carried to a convenient position by means of brass rod with necessary angles and links, then throttle the engine when releasing the reverse gear.
    Needle valve on carburetor should be regulated to get the maximum power from the engine and get sharp, clear explosion from each cylinder when priming cups are partially open.
