Lubrication

A gasoline motor requires ordinary intelligent care. It should be kept clean internally and externally. Grease and dirt form conductors, injure the insulation. See that no foreign substance enters the fuel tank, as a small particle will obstruct the needle valve. It is a good plan to have a gauze strainer in the funnel used to fill the tank. Never use ice for cooling parts that have become heated - cool gradually. Use a high grade gas engine oil for cylinder. This is a high fire test mineral oil - animal oils will not do.

A good grade of machine oil is suitable for shaft bearings and other working parts, or still better, use compression grease cups on all the main bearings.

If the motor lubricates the connecting rod by the splash system, the crank chamber should be supplied with " crank case oil." All parts must be oiled sufficient for lubrication. Beyond this, an excess of oil is a detriment, resulting in an accumulation of grease about the motor besides forming a gum that clogs the openings to the cylinder, the rings of the piston and the spark points.
