ABSTRACT:
A lubrication system for an engine having a fuel system including a floatless carburetor is disclosed. The engine has an intake system through which air is supplied to the engine, the carburetor associated with the intake system and arranged to deliver fuel into air passing through an air flow passage therethrough. The carburetor has a main fuel supply line extending between a fuel supply chamber and a discharge to the air flow passage, a first one-way type valve arranged along the main fuel supply line, a diaphragm dividing the fuel supply chamber from an air chamber, the air chamber coupled to an air source whereby movement of the diaphragm causes fuel to be discharged through the main fuel supply line to the air passage. The lubrication system is arranged to deliver lubricant from a supply through a lubricant supply line communicating with the main fuel supply line between the first one-way type valve and the discharge.
