To each his/her own but I personally keep mine in place but like Super said they should get cleaned every time you clean your carbs. The float pins are tight so you need to be careful. Alot of guys on here (including myself) use a spring loaded center punch to get the pins out. You do not want to break one of the float pin towers off while trying to tap the pins out. Plenty of info. on here by doing a search ie: float pins, center punch, etc.....
