The method I use is the following: Shut off fuel & purge (if LPG) ,Remove all spark plugs, remove dist. cap, place 1 finger in #1 spark plug hole ( if #1 is difficult to get to, any hole will due, just make a note of which cylinder you're in), crank engine over for about 5-10 seconds, watching where the rotor is when compression pushes against my finger.
