Its a PIA...but just look above the starter and there is a small hole you can see the fly-wheel. Best is thing is to clean the fly-wheel off and mark the ball with a white paint or correction fluid. Mark the timing pointer also with white paint. Dizzy turned CW is advance or BTDC turned CCW ATDC time it to the ball and go from there with your highest vacuum 17 to 21 back off a pound and you are good to go. The triangle is not the timing mark as pointed out here in the forum to me. This mark is to set-up the valve gear. Look for a small indented single metal BB its much smaller than what is used in a BB gun. I learned all this from this forum. These guys are the best. Like you I'm (still) confused but willing to learn. SJB
