With 76s the hesitation is now almost completely gone.

And to be honest, even though the carb came with the black secondary spring, I threw in the brown (next to heaviest) right after I got the spring kit.

I'm wondering if I should try 77s or 78s now on the primary and then bump up the secondary side to 84s.... thoughts?
