Before you rip into the OP, notice he is asking about an alternative to knowing if he is on the exhaust or compression stroke when #1 is at the top and the flywheel mark isn't available. That's a pretty legit question. The discussion strayed a little from what he asked so I will assume you just got confused. ;-)
FM - quick and dirty answer. Get everything lined up where you are confident you are either at TDC or 180 degrees off via the mark on the cam. Pull #1 plug. Stick your thumb in the hole and rotate the crank. You may need a friend to help. If you hear fart sounds its the compression stroke. AKA poor man's compression test.
Edit: You have to do 3/4 rotation of the crank after locking in what you think is TDC. So #1 is on its way up when you stick your thumb in the hole.
