Have you turned the crank a little each way past the marks you found? On mine the T is there and the marks you found as well. You do have to look closely to see the cross bar on the top of the T. Are you trying to do cam timing or ignition timing? You can pull the spark plug to avoid the crank turning past the mark. It's probably engine compression that's making it rotate past where you want it. It's also a good idea to use a socket on the flywheel bolt for precision in turning the crank.
