Unless you have a special head with two separate inlets, I would imagine one of those carbs would do the job easily.
Have a look at the blitz buggy link I posted somewhere.

i was just thinking of a 2 into one manifold to attach both to the head...

Wait, doesnt the bis have a twin carb?? What does this one do that the stock cant? Im not saying anything, just asking... 

[Paulh81]

Looks easy now ive seen this pic..  just a case of modifying the manifold and attatching to bent pipes... jobs a guden...

Id go for a tube based fanny mould, just make a set of flat plates to bolt to the carbs and engine then cut a piece of appropriate carved tube and weld it in between....

[Paulh81]

explain that a little better stuey... i was just going to use the gasket (pictured) as a template, and then machine it out of 10mm steel, the weld two pipes on to it..

My carbs have rubber connectors on them to connect straight to engine

[stuey]

ah then do what you said then..... I thought the carbs had a mounting plate of their own...
