Dave,  

I have had exactly the same experience as you.  I chased a "sputtering"
problem for the last two months because I have set my timing to 4deg
A.T.D.C.  After carb adjustments, new points rotor, fuel filter etc. . .  I
decided to just set the timing until it ran well.  Guess what? when I check
it with a timing light it is advanced off scale.  I don't understand why my
engine is so different than what has been documented.

Am I overlooking something or is there something that could possibly be 
detrimental to have the timing so far in advance?

I have also done some testing in terms of adjusting the timing and checking 
the temperature at idle.  I hate it when the needle rises above halfway 
(which on my car is 180).  I have a summer thermostat in the car (165) and 
when idling the needle now goes to just above halfway.

Sincerely,
Dave Herbert
