Are you referring to oiling the cylinders for long-term storage, like over the winter? I've always used a very simple procedure that involves running the engine at a fast idle and dribbling 20 weight oil down the carb throat until there's a heavy smoke from the tailpipe, and shutting the ignition off. Then stuff a tennis ball or something similar up the tailpipe and cover the carb air horn with a few layers of heavy plastic and some duct tape or a bungee cord. That seals the whole intake/exhaust system from moisture, and keeps mice and other vermin from using the exhaust system as a nesting area.
