Thanks for the help, Duc
As Wizby recommended, if in doubt richen the top, I would richen (counter clockwise) it for 1/4 of a turn and see if it improves, if it does then you know it is too lean, also make sure your pressure line is in good condition, if in doubt replace it with a new pressure line, I have experience that when it gets old it does collapse and restricts pressure going into the tank thus giving acceleration problems.
