Put 2-3 tablespoons of motor oil in each cylinder, and turn the engine through several revolutions by hand. Then crank it with the starter a few turns to be sure there are no tight spots. Give the valve guides a good squirt of KROIL, PB Blaster, or some other good penetrant before trying to turn the engine. WD-40 is not a good penetrant, BTW! It's best use if getting water out of places it doesn't belong, hence the "WD"- - -"Water Displacing"! Formula #40!
