You didn't switch the bearings side to side did you? Many years ago my brother once swapped the bearings by accident and it made an odd noise then failed shortly after.
Something I found to be helpful was I wrote down exactly what it was running like and then I noted the changes and how they affected the tune. Early on in my younger days I ended up chasing my tail a few times as I forgot where I was on springs, rods and jets after a few cold refreshments....lol!
Read the Edelbrock theory of operation if you already haven't. It's a great guide to fine tuning these carbs. Once you understand how they work, whatever condition you are chasing is easier to recognize and correct. (I had to read it several times till I got it) Lol...
