MG MGB Technical - Carb Sizes 1500cc

Hi Guys

I'm about to invest in some shiny new Speedograph air filters, but I'm a little unsure what carbs I have/should have. For some reason I thought remember reading that the default setup for a 1978 1500cc midget, are twin S.U. HS4 type 1.5" carbs ??

I emailed Speedograph and they said that they have 1.25" listed.

Does anybody know which they should be, and how to check which I have, i.e. what measurement is the 1.25 or 1.5" ? I have measured the diameter of the opening into the carb where the air filter attaches to, and this is 1.5", so I am guessing this maybe the dimension?

Any clues would be appreciated.

cheers

I *believe* that you may want to post this on the Midget BBS as well.
