After you put a couple tablespoons of 30 weight into each cylinder, hand rotate the engine to bottom out each cylinder one at a time and with a Harbor Freight air nozzle with the long skinny extensions (and don't use any tips that will fall off) stick it down the spark plug hole and hit it with a good shot of compressed air. That will spread oil all over the inside of the cylinder and maybe even use a rag to keep from oiling everything on the outside of the cylinder. This method is way easier than shaking the motor around in all directions like some other small engine versions of oiling the cylinder walls.
