How did you clean the carbs? Spray cans or did you dip them in Berryman's?

That's the most common mistake people make with Kat carbs. Soaking them in carb cleaner for ~24 hours is the only way to clean them. (Well, not only. Media blasting works, not everyone has access to that. Ultra sonic cleaning ive heard mostly positive things about so that might be viable too. Point being the inside passages/ports need to be cleaned out and spraying carb cleaner in them doesn't do it. )
Good luck!

Okay, my $.02 worth. For carb and brake parts cleaning I made my version of a redneck ultrasonic cleaner. I have a 1.5L commercial cleaner and this homemade version works better in multiples. I've included a picture and have a video of it working.

I went to my local mexican restaurant on salsa making Monday and got a 6-quart tin can. I ratchet-strapped a $10 HFT orbital sander to the side, cut a piece of rubber to keep the parts from bouncing around inside the bottom of the can, add a pint or so of Purple Power degreaser (or use whatever you like), filled to near the top with boiling water and turn her on for an hour. I'll put the small parts like jets in a small cup at the bottom and set the whole setup on a piece of carpet so it doesn't walk all over the garage floor.

I've also used a rubber tub to clean all four carbs without taking the rack apart or bigger parts but the action in the can works the best because the rubber tub absorbs some of the vibration.
