I have two small motors (a Honda outboard and a Kawasaki generator) that I

pull the starter to get the valves open)
However, I mentioned it to a friend and he says that is only good for a

Sometimes the valves will stick open if theres any moisture gets into the
guides and rusts the valve stems, the springs arent strong enough to
re-close the valves when this happens and then you will have to stick a

compression stroke to make sure both valves are in the fully closed position
after putting oil in the cylinder and before replacing the spark plug.
