Hesitation issues - need help

So, long story short, I sent the carb back to Holley just before Labor Day weekend, got the new one back from them today. Put it on tonight and everything is solved! Started right up, idled, took it out and no problems under any conditions - cruising, city traffic or highway. What a feeling! Thanks for all of your suggestions - I learned a lot through this process.

The only issue now is it's idling high and I've got to work out some issues with the throttle cable/pedal (not enough throw in pedal so not getting WOT). Piece of cake.

I did some searching around and found a fair number of threads about Holley issues similar to mine, and I'm thinking most are probably related to the same defect. Don't know if everyone who has experienced these problems knows about the defect, but certainly the word should be spread. And big kudos to Holley - they stood behind their product (that's what Made in the USA is all about brother!) and made it wicked easy to get my new carb.

Finally, a correction on my set up. I don't know what I was thinking but my cam is an XE262, not an XE268. Can't explain the brain cramp on that - I started a thread on this when I was trying to figure out which cam to go with a while back, got a lot of great replies and great discussion and the 262 was pretty much the consensus. I had initially been leaning toward the 268 but was ultimately convinced that it was too aggressive so maybe that's why it came back into my mind.
