John, When you set the static timing to -12 deg, the vacuum retard
unit, (if working) should bring the timing at idle to about 4 degrees
ATDC. Check your vacuum unit to make sure it is good, also make
certain that it's connected to the proper port on the carb setup. You
didn't mention what year your car was, the connections vary from year
to year.
Good luck,
