Abstract
A lubricating system for use in a two-cycle engine having at least one valve pivotally mounted through bearings in the sidewall of an intake passage of a carburetor is disclosed which supplies lubricating oil directly on the sidewall of the intake passage to lubricate the valve bearings in order to prevent corrosion and sticking of the valve. The lubricating oil is delivered into the intake passage directly on the sidewalls upstream of the bearings so that the lubricating oil flows along these walls to assure adequate flow to the bearings. The lubricating oil may be delivered into the intake passage by supplying the oil directly through at least one of the bearings of the valve.
