Hook up the vacuum gauge to manifold vacuum, and adjust one side for the maximum vacuum you can get. Then slowly close, or turn CW, until the engine starts to stumble. Turn CCW 1/4 turn. Do the other side the same way, and you'll have your idle screws set.

Some say adjust for max vacuum, but if you're looking to save gas, this will give the best idle/lean mixture combination.

thanks lindel . so what are the pros and cons of max vacume settings. if the vacume is now differing from when i last set my timing should i reset it because of vacume advance vacume changing?or will the vacume advance vacume stay at a constant regardless of manifold vacume changes? thanks again
