Hi chevetter
There are several different "sets" of CD150 carb families. The Jets and needles are ususally interchangable unless they are of the later type (alla chevette) which have the emission control bits and spring bias needles.
As you know, my 1280cc engine ran nice on the setup I had, so I can have root about and get the jet info to you some time soon.
My carbs came from a GT6, and are CDS150's
I'll try to get back to you soon
Cheers
