Abstract
A rail saw has a power head which includes a two cycle engine which does not require premixing of gasoline and lubricating oil. Instead, undiluted gasoline is stored in the engine's fuel tank, and lubricating oil is supplied to the engine's fuel supply system downstream of the fuel tank by a mechanical metering pump which delivers a designated, preferably adjustable, quantity of oil to the fuel supply system per engine revolution. In the case of a power head formed by converting a chain saw power head to a rail saw power head, the oil supply system may comprise the lubricating oil system originally designed to lubricate the chain saw's chain. Also disclosed is a preferred method of converting a chain saw power head requiring the storage of a premixed gasoline/lubricating oil mixture in its fuel tank to a rail saw power head whose fuel tank stores gasoline only.
