The bike is a gas gas txt pro 125 2007

I have a gas gas txt pro I recently baught and I was told to clean the carb when I got it which I did. I went to put the carb back on and noticed it wouldn’t properly attached to the air box and now the bike isles perfect but when I give it throttle fast it bogs. Is this because there is too much air getting to the carb as the air box won’t attach or do I am have another problem
