That depends, do you want to get better gas milege or not?
You can change to different metering rods on those carbs. They have steps in them.
You need to measure the different steps in the rods & come up w/a leaner mixture @ idle so it does not smell so rich.
The fatest part of the metering rod is your idle.Try & find metering rods that are simular insize(the other two or so steps) but a little thicker at the idle section (top, thickest portion)
The slimest part on the metering rod is the wide open throttle (used when your engine produces no vacuum,, area)
