Stopping the Engine 1. Shut off gasoline at needle valve. Turn off oil at lubricator. Shut off gasoline at supply tank. In cold weather be sure to drain the water pot thoroughly by taking out plug under the cylinder.
Cautions Keep the water pot half or three-quarters full of water.
Never allow the water to get below the joints of the water pot on the cylinder. The four principal causes of trouble on a gasoline engine arise from Poor Ignition, Loss of Compression, Poor Lubrication and Loose Bearings. Of these four the last one must be guarded against most carefully. Just as soon as an engine bearing gets loose and begins to pound, it should be looked after, removing enough of the shims to take up the wear. If this is not done, the engine will rack itself to pieces.
