surges after running for awhile

mmmm spent a lot of time on it tonight.

check compression, good...
new plugs
new condensor and cap, would have put new points in but crap the give you at Kragen is all wrong all the time....

shes real happy when I stomp on it. but she dont like idle at all nor light throttle.. seems the idle and cruse circuits are not getting enough fuel or something...

how does one change the fuel supplied to thes circuits on the edelbrock 1406? jets or float? i must find out... I have a new 1406 sitting on my table but would much rather figure whats wrong and fix so i can get the 300$ back for that new carb...
