NEED some help....idle issues after cam swap...

Alright sorry I was away today as for what we did for install, we lined the Dots up, the car ran fine before the cam, all you had to do was hit the gas one time for the electric choke and it fired right up and idled great, we put this cam in and it fired right up on the initial start, we got everything broke in then went to get the idle set and now have this issue. We have a carb on another 340 with the 284/484 cam that we know starts and idles great so I guess we are going to make sure the timing is set like you guys all said in other comments and put that good carb on it and see what happens...
