I recently cleaned my carbs and sprayed these rubber seal things on top of the carbs with carb cleaner. I later learned that i shouldn't have done that. Anyway now when i put the carbs back together and on it ran like crap. Popping like crazy and seemed to have no "getup and go". I couldn't pull a wheelie. So do I need to replace these? How much do they cost, I can not find them on the internet?
