Hi Jeff, It's been a while & I was wondering how you are doing ? I found a glitch in my Sprint. The carb. always had a slight flat spot ( hesitation ) under hard acceleration. Turns out the secondary upper flaps had a notch in them that was causing a bit too much air flow. I pulled the upper secondary flaps off a spare carb. ( no notches ) swapped them & bingo ...no more hesitation ! I only found the difference in flaps when I was looking at the carb. on the test stand and noticed it did not have the notches , like the one on the car.
