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.
