Larry,

My method is to set the crank at TDC using the indicator on the crank pulley 
and then set the distributor so the points are just opening using a 12v light 
bulb (one of those dash bulbs), By attaching a bulb to the points and then 
ground you can then move the distributor back and forth until you get to the 
approximation. I made a little harness with a spare bulb socket and wire 
clips.

Once that is done, set the distributor advance to 4 degrees advanced and you 
are at a good starting point.

Remember to tighten down the distributor and start the engine.

Now I adjust the timing by "ear" with the engine running by using the 
micrometer adjustment on the distributor advance. When it sounds ok, I take 
it for a spin to insure no knock and good power, acceleration.

This method has always worked for me and both the 3 and 4 run just great.

I think this method is described in the manual somewhere.
