I'm a know nuthin' 'bout carbs just like you.

Here's some decent carb photos from some new guy that
joined up with us. Looks to me like he might know a thing
or two.

If this doesn't help ya, I'm sure some folks would take a few specific photos for you.

Regards from ten thumbs Tinster.
PS: Don't forget to powdercoat the tops to match your car!

Plus he's a really good guy.

NO pics here, but I have been considering the conversion myself.
This is what "I think I know". The fuel comes into the float chamber with 2 nipples. Enters one nipple then splits off and exits via the other nipple to the 2nd carb's float chamber.
You MAY also have 2 vacuum ports with similar size nipples that are for the valve cover ventillation hose connection. These are on the carb body proper.

They are Spits but Spitfire and GT6 magazine Photo Pages (https://www.triumphspitfire.com/enginephotos.html) has several pics of dual SU setups. Go to the "slightly modified" section. Rimmer Bros. probably has the stock linkage setup for dual SU's
