You can use nc30 carb rubbers, no problems at all.

Genuine parts can be had from the usual sources or there are cheaper pattern sets on ebay.

Erm.

NC21 has 30mm carbs.

NC24 /30/35 has 32mm carbs.

The actual carb body is the same on all carbs, but the later models are bored out more.

This would present a problem trying to use the NC21 rubbers with later carbs as the inlet is too small

I don't think the reverse is true but you dont' have much choice as the NC21 rubber is discontinued and unavailable.

If you phone David Silvers they'll be able to get the parts without the part number, if you want to order online from either vendor just put the following part number in.

www.lings.com -> Click Original Honda Part
www.davidsilverspares.co.uk -> Click search by part number

16211ML0000 - NC21 - No longer avilable.

16211ML0720 - NC24 carb rubber.. around 6gbp I believe (and avilable)

NC30 uses the same carb rubbers as the NC24.
