Lazy off the line

[Run to Rund]

I agree with the above advice. When I read the initial post, I felt the carb was too big, the intake too aligned to high rpm (especially depending on how it was ported), and the rear gears too mild. Yes, the carb and intake may match the ported heads, but the overall result is consistent with a high rpm combination, and is being killed by a low rpm combination elsewhere.
