Abstract
A lubrication system for a two-cycle engine includes an oil delivery system for delivering oil to an air intake passageway of the engine. Oil is mixed with the intake air in the intake passageway and is then carried by the intake air into the crankcase chamber and combustion chamber, thereby lubricating the components therein. The oil delivery system includes an oil discharge pipe in communication with the intake passageway and is generally located adjacent an upper surface of the intake passageway.
