Holley 80457-2 stumble

Like I said, this looks all too familiar to me. Maybe some others have different thoughts. I just wanted you to know what I would personally do in this situation. Good luck and let us know any results you get. Just trying to be helpful.

Ordered the jets 64-99 from summit, might be here by Saturday??
I also ordered the 50 cc kit and extra pump shot cams, but I should not need these on this stock engine, but I can use them on other engines I have.
I will let everybody know of the results.
Thanks everybody.
Shawn
