There are some real small passages in those carbs but once clean and sealed, they run real well. If you have access to an ultrasonic cleaner, or buy a jewelry ultrasonic cleaner maybe on amazon, or buy the one gallon Gunk carb soak and soak for a week. Follow up with chasing passages with speaker wire strands, carb spray and compressed air. Mounting flange- check flatness, use small thick flatwashers not lockwashers. Use original jets and not ones that come with carb kits.

Also make sure the mounting spacer is flat, new o-ring, base gasket, Hondabonded.

Any little airleak in the setup makes them sputter and not return to idle fast enough for a smooth shift. I have gone through every leakpoint by replacing the little o-rings in the carb.
