Hello all, thanks for your time.
I have a 1968 mustang with a newly re-bult 302. The heads were mildly
ported and fitted wiht oversized valves, and It has a comp cams cam
with .456" lift and ~260 degrees duration (i think) set to about 16
degrees advanced (cam manufacturers recommendation) and a 625cfm road
demon jr. The carb's butterflies are set according to the manual,
along with float levels. The engine surges a little bit at idle, and
when shifted into gear (auto tranny) it either dies or will die soon,
or bogs and dies when I try to acclerate. I think it has something to
do wiht the idle mixture, becasue the manual doesnt explain well how
to set it, and I'm not good at telling whether it is rich or lean. the
idle is set at about 650 rpms. Any help, tips, or ideas would be
greatly appriciated.

Thanks!!!
