Default Rebuilt 400 HO suddenly runs rough

Car runs 1000x better! No stuttering or stalling accelerates great! Thanks so much for all the help! You guys rock!

The last annoying things are, when I come to a stop, it’s idling at 1200, but if I kick the throttle it goes back down to 800. It did not do this with the previous carb.

To Steve’s point: I drive it for about 20 miles (local). When I shut it down, it dieseled a little. And once it was warmed up, it took a bit more cranking to get it started. Should I move the timing to 38 (with vacuum advance disconnected)?
