[tech]: help with fast idle? anybody?

["Michael Abatzis" <abatzis2@hotmail.com>]

my car is finally up and running well. figured out my timing issues (mixed 
up the marks on the flywheel), set my mixture and idle with a dwell meter. 
unfortunately, when everything is set correctly, the car idles at 1400 rpm. 
when the idle bypass screw is turned all the way closed, it still idles at 
1200 (dwell is then about 22).  any thoughts? maybe a vacuum leak. i can't 
find one. maybe a busted idle air bypass valve? would that do it? how about 
an exhaust leak? i think i may have developed one, but i've had em before 
w/o it messing with the idle; unless it was upstream of the o2 sensor? i'm 
so close! c'mon, help a brother out!
