I just had the same puzzling situation, tried all kinds of tricks, but nothing. I did a search here on the site and found a great solution.
Here’s thanks to msprecher who posted the idea originally.
Go to Home Depot and buy this magnet:

Come back to your shop and stick the magnet on your flywheel, behind but up snug against the starter ring. Put your car in gear and push to rotate the engine a full revolution. Here’s what you’ll see. I borrowed the picture from the thread that gave me the idea. Good luck with it!
P.s. You’ll have two magnets in the Home Depot pack, so give one to a Model A friend. I did!
