I recently went through similar problem... hesitation taking off normally from a stop light I could fix with about 2 degrees more advance. Launching hard (flooring it) I went up on pump nozzle size to squirt sooner (I'm assuming this is a double pumper?) from #31 to #40 was too far... #37 sounds about right 63BoxNova...

Is the acc. pump squirting with a very small throttle opening? Holleys use a cam to actuate the pump, can you move the cam so it works the pump sooner?

Yep. It’s pretty sad.
