It's pretty much what I'd expect to get charged if they've done what they claim.
The carb rubbers do get cracked with age and sunlight. They can look very bad before they crack all the way through as they're quite thick, but it's possible they have done that in your case. The result will be too lean a mixture at idle... which can be offset by the use of the choke.
Before spending lots of money on replacements, get some ordinary black silicone sealant and smear it into all the cracks. If that cures the problem it'll do as a temporary fix.
Otherwise, cleaning the carbs out is probably what's needed.
