Just grab the rotor and twist it fairly hard. There will be some play
in the shaft, but you should not be able to turn it any further than
the spring loaded advance allows. If it's not fully engaged in the
drive gear it will slip and stop in another location. If that
happens, loosen the clamp and turn the rotor while pressing down.
When it reaches the right spot it will drop down almost 1/4", but
there are other places where it will seem to just catch. Ignore the
places that just catch.

There are 2 kinds of failures that give these symptoms and both get
described as valve seat recession. In one case the valve seat
actually moved down into the head; in the other the seating surface
wears away drastically. In both cases the valve has to be reset
frequently, and in large amounts.
Which case did you have?
I had a seat which wore down, but didn't move. I figure that head can
be saved with a new seat insert.
