Yup right on! You'll want to set each screw for fastest idle-speed with each cylinder on hot engine (then +1/16-1/8). Then re-adjust idle-knob afterwards for factory idle-speed. Done!
Any other issues after that in off-idle transition or mid-range is due to insufficiently cleaned secret hidden passages in carbs. Jets are just first 5% of carb-cleaning, there's plenty of passages that flow petrol before and after jets that needs attention as well.
These nifty little suckers really help!
