The ultimate timing position you are looking for is to have the points break at 22 degrees before top dead center.

To accurately do this you will need a degree wheel, a volt-ohm meter, and a feeler gauge.

You are going to need to have an idea of the relationship of the crankshaft Key way to the top dead center position if you are going to do this with the flywheel removed?

The volt-ohm meter or even a self powered test light is required to know just when the points break.

The feeler gauge is to set the point gap in order to have the proper coil saturation dwell time.

You will need a piston stop to use with the degree wheel to find top dead center. I have been successful in determining TDC with the degree wheel attached to the crankshaft alone without piston stops and all that jazz. Just determine the center of the dead zone at the top of the compression stroke by feel.

If you need a degree wheel, there are many on the internet that you can print out and glue to a piece of card board, metal, or plastic that will work very well for this purpose. I can give you links if necessary?

If all this is getting too complicated for you, just set the points at .010" and put the timing marker on zero. Don't worry about the rest if it runs good . . .
