They need more work than that:

- carbs needs to be disassembled down to every last nut, bolt and individual component

- everything soaked in ultrasonic cleaner

- secret hidden passages need to be mechanically scrubbed with brushes using strong solvents and PEA-based cleaners

- jets and emulsion-tube bleed holes needs to be flossed with matching gauge wire

- micro soda-blasted

As compared to before, your cleaning did improve performance, but deeper cleaning more thorough restoration job is needed.
