Take out number one spark plug… Put thumb over hole tight and turn the engine over until it you feel compression with your thumb. Look through the hole to the flywheel. If you see the timing marks you are on the compression stroke and not the exhaust stroke. After bringing number 1 up on the compression stroke and seeing the timing marks through the hole to the flywheel… Take note of where the rotor is pointing. 
That will be your number one spark plug wire hole in the cap.
