Is the car still using the vacuum tank? If not, is the new needle and seat calibrated to handle higher pressure than gravity feed?

There is supposed to be a bleed passage that pulls fuel above the throttle plate at idle the same way as idle air bleeds on a downdraft carburetor. If that is clogged the motor will load during idle.
