It's there on the flywheel. Hint: If you can't find it, rotate the shaft till one set of points is about to open. The marks should be somewhere close.

The timing marks are for setting the points with a timing fixture special tool.

Timing fixture can be bought here from a certain skilled tool maker. He roams these parts now and then ;)

If you set your points correctly at .020 " the timing marks will be right on.

In theory that is correct. However, I have never had them perfect with feeler gauge alone. Gets you close though. You are likely more experienced with them.

The best part about the timing fixture is it gets them to fire EXACTLY 180 degrees apart. That makes for a perfect, low idle. I don't use feeler gauges anymore myself unless Im out in the country without my full tools.

Thanks for the replys. I set the points to .20 , but I still can not find any timing marks on the flywheel. I cleaned it and inspected very closely, but can not find any. Any suggestions appreciated.

They're on the very bottom of the flywheel. With a timing light they should fall between the two marks on the armature plate.
