they pop out straight down , keep pressing down and they will push the little round brass plugs out with them(#2 has that plug drilled) (take float bowls off),have te be carefull take it slow,,i had to remove them cause i f##ked them up trying to oversize the tiny holes with a micro drill bit,good thing i had some extra carbs laying around, i replace all four squirters,, this time i just cleaned up those super tiny holes with a wire from a steel bristle brush perfect size to clean them,those holes are super tiny ,,,you don't have to mess with them but if your an idiot like me you will,,,ah sometimes it takes mistakes to learn something , all i know is that those squirters are squeaky clean now with a good even spray pattern
