"boil the carb" - OOOuuuccchh!!!!!
By all means - take the bowl off and give the carb a good wash in hot (not boiling) soapy water and then thoroughly rinse with fresh water and blow out all the carb ports and vents and see how you go.
The problem with boiling up a carb is there are plastic parts in there and if you boil them up, they can often distort, and with carb parts - distortion = death to them
