the vacuum advance is hooked up to manifold vacuum and the other port on the metering block is plugged. as for the timing i will prob try bumping it ahead to 15-20 as you guys recommend. i thought about modifying the carb or getting a bigger one because i thought the same thing that the carb is idling on the main metering circuit and i need to let more air by.
i dont know the affect changing the timing will have though. i only have the idle speed screw up this high because it needs it to run because the motor will not idle which still leads me to believe i have a vacuum leak. i still havent got any time to start up the car and run it again though so i havent gotten any further. by drilling the throttle blades i will be able to keep the idle speed screw turned in farther but not draw as much fuel correct?

i will get back to you guys as soon as i get to run the car again.
thanks for all the help so far
