Idle

Idle is going to be that little screw with the spring on it on the carb, turn it in more idle counter clockwise less idle. Also, you can adjust that cable on the top till its snug.

Lots of good suggestions. If you dont have any vacume leaks, (carb to manifold/manifold to head) it will take a good 25 miles for the idle to stabilize. Ive started all my new builds by turning the idle screw all the way in till barely snug, then back out 4 full turns. Then "tweek" from there. Also make sure the cable adjustment on the top of carb (cap) Is snug but not too tight, or the ilde will be a little high and make the idle screw unadjustable/responsive.
