Bogging down

[Mustang]

well bugger, after removing the carbs and airbox Tuesday I cleaned the outsides of the carbs as well as I could then took off the float bowls one at a time, took off the jets and nozzles only and gave them a blast of carb cleaner. I didn’t take off the floats or the carb tops. Now when I’m riding it bogs down over 6k revs in top or 9k revs in 2nd or 3rd. Is this likely to be carbs blocked or an air leak? It rides ok at low revs.
